Service Manual Supplement INTRODUCTION General Information This manual applies to the following ROUSH CleanTech Liquid Propane Injection applications: • 2009–2010 F-250/F-350 5.4L-3V This manual is a supplement to the regular Ford Workshop Manual, covering the unique components of the ROUSH CleanTech Liquid Propane Injection system: • Fuel supply line • Fuel return line • Flow Control Solenoid (FCS) • Fuel rails • Fuel filler lines, valve and filter • Fuel tank The ROUSH CleanTech parts generally serve the same functions as the Ford parts they replace. The online Ford Workshop Manual, if available, continues to apply to all other details. The diagnostic chart in this manual directs the technician to appropriate sections of the Ford manual for applicable remedies in some situations. Propane, like other fuels, must be handled safely with knowledge of its characteristics. Training in propane characteristics and handling is available through the Propane Education and Research Council (PERC), 1140 Connecticut Avenue, Washington, DC 20036. Their web address is www.propanecouncil.org. ROUSH CleanTech Technical Assistance Call ROUSH CleanTech customer service at 800.59.ROUSH with any questions regarding ROUSH CleanTech Liquid Propane Injection systems. Start Sequence The Roush CleanTech Liquid Propane Injection system is fully integrated with Ford’s One Touch Starting system. The vehicle operator turns the key to the Start position and releases it. The computer senses the pressure/temperature in the fuel lines and starts the fuel pump. The pump sends liquid propane through the lines driving the vapor back to the tank to become liquid again. When the pressure/temperature sensor reports that the lines are full of liquid, the computer energizes the starter and the ignition system. The entire sequence generally takes from 1.5 to 10 seconds (may extend to 20 seconds under extreme ambient conditions). Fill Stations Propane is readily available anywhere in the United States. To locate the nearest station, check with http://www.afdc.energy.gov/afdc/locator/stations/. 2/11/2011 Current as of 2-11-2011 1 ROUSH® CleanTech F-250/F-350 Liquid Propane Injection Service Manual Supplement ROUSH CleanTech recommends facilities designed for automotive refueling. Other locations may have low output pumps, resulting in slow or no fill, or low quality fuel which can result in premature component failure. Range and Fuel Economy Propane contains less energy per unit volume then gasoline. Therefore, customers will generally experience fuel economy (mile per gallon) 15–30% lower than gasoline. Vehicle range will vary based on driving conditions and loading. Safety Information The National Fire Protection Association (NFPA) publishes a code book of rules that apply to the storage, handling, transportation, and use of liquefied petroleum gas (LP-Gas or LPG). The book is known as NFPA 58. It is revised as necessary and published every other year. This code is adopted as law in virtually every political subdivision in the United States. Check with your local authorities for regulations applicable to liquid propane. Alert Messages The following alert messages appear from time to time inappropriate places in this manual. Ensure that all personnel in the immediate area are aware of these reminders. Danger: Although propane is nontoxic, nonpoisonous, has the lowest flammability range of any alternative fuel and dissipates quickly when released into the atmosphere, propane vapor is heavier than air and seeks the lowest point. When the ratio of propane to air is between 2.2% and 9.6%, propane will burn in the presence of an ignition source at 940°F (504°C) or hotter. Keep away from heat, sparks, flames, static electricity or other sources of ignition. Failure to heed this danger may result in severe personal injury or death. Danger: The fuel supply lines remain pressurized after engine shutdown. Keep away from heat, sparks, flames, static electricity or other sources of ignition. Do NOT enter storage areas or confined space unless they are adequately ventilated. Failure to heed this danger may result in severe personal injury or death. Danger: Do NOT carry lighted smoking materials or smoke while working on fuel system components. Failure to heed this danger could result in severe personal injury or death. Danger: Disconnect the battery ground at the battery to ensure that the vehicle electrical system has no current. Failure to heed this danger could result in severe personal injury or death. 2/11/2011 Current as of 2-11-2011 2 ROUSH® CleanTech F-250/F-350 Liquid Propane Injection Service Manual Supplement Installation, Garaging and Training Chapter 11 of NFPA 58 applies to engine fuel systems using LP-Gas in internal combustion engines, including containers, container appurtenances, carburetion equipment, piping, hose and fittings and their installation. Additionally, this chapter applies to garaging of vehicles and to the training of personnel. Paragraph 11.2 specifies that each person engaged in installing, repairing, filling or otherwise servicing an LP-Gas engine fuel system shall be trained. Contact the Propane Education and Research Council to learn more about their CETP E-Learning computer-based training program: [email protected], or [email protected]. Purging and Venting (Tanks and Lines) Venting of LP-Gas to the atmosphere is covered by paragraphs 7.3.1, General, and 7.3.2, Purging of NFPA 58, 2008 edition. Refer to NFPA 58, Local Codes and Proper Training for specific information relating to safe venting of LPG. 2/11/2011 Current as of 2-11-2011 3 ROUSH® CleanTech F-250/F-350 Liquid Propane Injection Service Manual Supplement VEHICLE INFORMATION Build Data ROUSH CleanTech emissions certification information is recorded on the ROUSH CleanTech Vehicle Emissions Control Information (VECI) label. The label is vehicle-specific and is required by law to be on the vehicle to which it is assigned along with the Ford VECI label. Vehicle Emissions Control Information (VECI) Labels SAMPLE Figure 1 — ROUSH CleanTech VECI Label (Typical) SAMPLE Figure 2 — Ford VECI Label (Typical) 2/11/2011 Current as of 2-11-2011 4 ROUSH® CleanTech F-250/F-350 Liquid Propane Injection Service Manual Supplement VECI Label Location The ROUSH CleanTech VECI label appears along with the original Ford VECI label in the following location: • F-250/F-350 — under hood at side near hood prop, passenger side Figure 3 — VECI Label Location 2/11/2011 Current as of 2-11-2011 5 ROUSH® CleanTech F-250/F-350 Liquid Propane Injection Service Manual Supplement DESCRIPTION AND OPERATION System Overview The ROUSH CleanTech Liquid Propane Injection (LPI) system consists of a propane fuel tank, fuel pump, fuel rails and lines, injectors and electronic controls. The system is simple and easily serviced with no user adjustment required. Figure 4 — ROUSH CleanTech LPI Fuel System — Under Vehicle Tank (Typical) Figure 5 — ROUSH CleanTech LPI Fuel System — In Bed Tank (Typical) 2/11/2011 Current as of 2-11-2011 6 ROUSH® CleanTech F-250/F-350 Liquid Propane Injection Service Manual Supplement Propane is stored in the vehicle fuel tank under pressure as a liquid. The pressure in the tank is determined by the temperature of the fuel, ranging from 0 psi at minus 44°F, to 312 psi at 145°F. The tank has an overpressure safety device which vents the tank at pressures over 312 psi. There are two propane filters in the system. The primary filter is located in the fuel fill line which is intended to filter out the majority of contaminants that may be present in the fuel. The primary filter must be replaced every 50,000 miles. A secondary fuel filter is located after the fuel pump inside the tank which is intended to ensure that no contaminants reach the fuel injectors. ROUSH CleanTech LPI vehicles require HD-5 propane, rated for automotive use. Use of HD10 or other substandard propane may result in excess contamination of the system and failure of the fuel pump, injectors and in-tank filter. A pump inside the tank delivers liquid propane to the injectors through the fuel supply line and the fuel rails. Excess fuel flows back to the tank through the fuel return line. Fuel pressure is regulated by the Flow Control Solenoid (FCS) which includes a small orifice to restrict return flow in normal conditions; and a bypass circuit to allow maximum fuel flow prior to engine starting or during extremely hot conditions. The FCS is a separate component in F-250/F-350 applications and is mounted on the left frame side rail. In order to safely store pressurized liquid propane in the vehicle, the fill system must ensure that the tank is not filled beyond 80% of its total volume. This ensures that sufficient expansion volume is present in case of significant tank temperature changes. The fuel fill system includes the following components: 1. Fuel fill valve, cap and mounting bracket 2. Fuel fill hoses 3. Fuel fill filter 4. Fuel tank internal components a. Fuel fill solenoid b. Fill pressure switch c. 80% level sensor During a fill event, the system functions as follows: 1. Customer connects fuel filler nozzle to fill valve and activates the fuel pump. 2. Fuel pressure in the fill line causes the pressure switch to close. In order for the switch to close, pressure in the fill line must be at least 10 psi higher than tank pressure, otherwise no fill is possible. 3. The fill pressure switch provides a ground to the 80% level sensor to activate the circuit. If the fuel level is below the 80% level, the sensor provides ground to the fuel fill solenoid, allowing fuel to enter the tank. 4. Once the fuel reaches the 80% fill level, the 80% level sensor de-activates, causing the fill solenoid to close. Note — Some fuel pumps may have sufficient pressure to allow a small fuel flow into the tank even with the fill solenoid closed. The operator should stop the fill as soon the fuel flow drops noticeably. 2/11/2011 Current as of 2-11-2011 7 ROUSH® CleanTech F-250/F-350 Liquid Propane Injection Service Manual Supplement Vehicle Starting The ROUSH CleanTech LPI system is fully integrated using Ford’s One Touch Integrated Start (OTIS) system. When the ignition key is turned to crank and released to the On position, the PCM opens the Flow Control Solenoid (FCS) and engages the fuel pump. As soon as the fuel rail temperature and pressure are acceptable to ensure liquid fuel at the injectors, the starter engages and the vehicle starts with no further action required from the operator. This delay period is usually less than 5 seconds, but may be up to 30 seconds in extremely hot conditions. During the delay period, the wrench light on the dash blinks to signal that the system is active. System Components and Function Fuel Rails and Injectors The Ford OEM fuel rails and injectors are replaced with ROUSH CleanTech LPI fuel rail and injector assemblies, including injection pressure and temperature sensor (IPTS), Schrader port for service and crossover fuel line. Figure 6 — Fuel Rails and Injectors 2/11/2011 Current as of 2-11-2011 8 ROUSH® CleanTech F-250/F-350 Liquid Propane Injection Service Manual Supplement Flow Control Solenoid (FCS) On F-Series vehicles a Flow Control Solenoid (FCS) is used to control fuel flow through the fuel rails. The FCS is installed in the fuel return line and mounted on the left frame side rail in the under-cab area. Figure 7 — Flow Control Solenoid Injection Pressure and Temperature Sensor (IPTS) The IPTS is used to monitor fuel pressure and temperature. On F-250/F-350 applications the IPTS is read directly by the PCM. Figure 8 — Injection Pressure and Temperature Sensor 2/11/2011 Current as of 2-11-2011 9 ROUSH® CleanTech F-250/F-350 Liquid Propane Injection Service Manual Supplement Fuel Supply and Return Lines The Ford OEM fuel lines are replaced with formed stainless steel lines following the original production line routings. The formed lines are produced in many lengths and configurations to accommodate the various vehicle models. The lines may be installed with two or three sectioned assemblies depending on the specific vehicle model. All sections, supply and return, include unions as part of the assembly. The stainless steel fuel lines are retained in the chassis using the Ford OEM retention clips. Figure 9 — Stainless Fuel Supply and Return Lines (Typical) Fuel Tanks Different tank configurations are used based on the vehicle model. A long cylindrical tank mounted under vehicle is used for F-250/F-350 LPI vehicles. Optional on F-250/F-350 models is a large-diameter cylindrical tank mounted in the pickup bed. The in-bed tank with its greater fuel capacity provides extended range.

These include the Multivalve assembly, Fuel Control Solenoid, Fuel Fill Solenoid, 80% Level Sensor, Fill Pressure Switch and the Fuel Level Sending Unit. Multivalve Wiring Pass-Through Overpressure Relief Manual Shutoff Supply Solenoid Fuel Fill Fuel Supply to Engine Fuel Return Figure 12 — Multivalve Assembly The Multivalve attaches directly to the fuel tank and serves as the main interface between fuel tank and vehicle. As the name implies, the Multivalve consists of a number of valves incorporated into one unit. The included valves are: 2/11/2011 Current as of 2-11-2011 11 ROUSH® CleanTech F-250/F-350 Liquid Propane Injection Service Manual Supplement Fill Valve — Located where fuel enters into the fuel tank, the fill valve is opened electrically by the Fuel Fill Solenoid during the fill process. It also incorporates double back redundant check valves which close when vehicle tank pressure is greater than pressure outside of tank to prevent fuel from escaping. Manual Shutoff Valve — This manually-operated valve is used to seal the outlet of the tank during shipping or service. It should always be open when the vehicle is operating. Excess Flow Valve — The excess flow valve is located in the supply fuel path. The valve is intended to shut off fuel flow from the tank in case the supply line comes off of the tank. If the excess flow valve trips (may happen after servicing the system), it can be reset by closing the manual shutoff valve and then slowly opening it. Pressure Relief Valve — When conditions cause tank pressure to rise to 312 psi, this valve automatically opens to relieve the excessive pressure inside of the vehicle fuel tank. Propane vapor is vented out of the pressure relief hose. Fuel Supply Valve — The fuel supply valve is controlled by the PCM and is activated whenever power is supplied to the fuel pump. Fuel Return Check Valve — The fuel return line is protected by a check valve in the Multivalve which prevents fuel from flowing from the tank into the return line. FUEL LEVEL SENDING UNIT The Fuel Level Sending Unit is located inside of the fuel tank and consists of a float on an arm with a wound resistor. The sending unit resistance is used by the instrument cluster to indicate fuel level and by the PCM. It is not used in the fill system. 2/11/2011 Current as of 2-11-2011 12 ROUSH® CleanTech F-250/F-350 Liquid Propane Injection Service Manual Supplement Fuel Filler Valve and Fill Line The fuel fill line includes the fuel port with fill valve, the fill line hose and a filter. Figure 13 — Fuel Filler Neck, Fill Lines and Filter FILL VALVE The Fill Valve serves as the fuel fill inlet to the vehicle fuel tank. This is where the fill station hose attaches while fueling and the fuel cap attaches during vehicle operation. It is a one way single back check valve that opens during the fuel fill process and closes when fueling is complete, to minimize fuel from escaping. IN-LINE FILTER The fuel filter is located in the fuel fill line to filter fuel from the fill station before it enters the vehicle fuel tank. The filter is field serviceable and should be replaced every 50,000 miles. 2/11/2011 Current as of 2-11-2011 13 ROUSH® CleanTech F-250/F-350 Liquid Propane Injection Service Manual Supplement Glossary 80% Level Sensor — An infrared sensor designed to detect the presence of liquid. The sensor is located inside the vehicle fuel tank at the 80% full level. Bleed Solenoid — Closed when the engine is running, sealing the fuel rail from the vehicle EVAP system. After the engine is turned off for approximately one hour, the Bleed Solenoid opens for a calibrated length of time allowing pressure to bleed from the fuel rails. When pressure is fully bled off, the solenoid closes, preventing fuel from entering the EVAP system. The bleed solenoid is located in the FRPCM. Fill Pressure Switch — A normally open pressure sensing switch. The switch is attached to the Multivalve, internal to the vehicle fuel tank and used to sense pressure of the fuel coming into the vehicle fuel tank from the fill station.

Ensure that all personnel in the immediate area are aware of these reminders. Danger — Propane is nontoxic, nonpoisonous, has the lowest flammability range of any alternative fuel and dissipates quickly when released into the atmosphere. Propane vapor is heavier than air and seeks the lowest point. When the ratio of propane to air is between 2.2% and 9.6%, propane burns in the presence of an ignition source at 940°F (504°C) 1 or hotter. Keep away from heat, sparks, flames, static electricity or other sources of ignition. Failure to heed this danger can result in severe personal injury. Danger — Fuel supply lines remain pressurized after engine shutdown. Keep away from heat, sparks, flames, static electricity or other sources of ignition. Do NOT enter storage areas or confined spaces unless they are adequately ventilated. Failure to heed this danger can result in severe personal injury. Danger — Propane is heavier than air and seeks the lowest available level when released to the atmosphere. Keep heat, sparks, flames, static electricity or other sources of ignition out of the area when venting or purging the fuel lines or tank. Failure to heed this danger can result in severe personal injury or property damage. Warning — Liquid propane is cold. The temperature of propane in its liquid state is -44°F (42°C). Wear eye and ear protection during venting and repair operations. Keep moisture away from the valves. Failure to heed this warning can result in personal injury. Note — Identify the condition (good, stuck open, stuck closed or inoperable) of each solenoid valve prior to venting the fuel tank to ensure that the solenoid valves are not the reason for vehicle service and unnecessarily venting the tank. 1 Gasoline auto-ignition occurs at a much lower temperature: 430°–500°F (221°–260°C). 2/11/2011 Current as of 2-11-2011 40 ROUSH® CleanTech F-250/F-350 Liquid Propane Injection Service Manual Supplement Changing Fuses Figure 23 — Fuse Panel The fuse panel is located on the bulkhead under the hood on the driver’s side. Figure 24 — 20 Amp and 15 Amp Fuses Always use a fuse of the correct amperage when replacing fuses. 2/11/2011 Current as of 2-11-2011 41 ROUSH® CleanTech F-250/F-350 Liquid Propane Injection Service Manual Supplement Pressure Relief There are two means of relieving excess pressure in the tank; the pressure relief valve in the Multivalve and the bleeder valve in the tank wall that is separate from the Multivalve. The pressure relief valve in the Multivalve vents excess pressure to the atmosphere through a hose that directs the release to a point at the bottom of a rear wheel opening. The pressure relief hose clamps to an elbow that attaches the cover to the Multivalve. The pressure relief hose, elbow and Multivalve cover are removable while the tank is in the vehicle. The bleeder valve in the tank wall vents immediately to the atmosphere. This valve can also be serviced using a standard box end wrench while the tank is in the vehicle. Purging Clearing the propane out of the fuel lines (purging) is required before attempting to remove any of the components. Following the suggested techniques for purging will discharge a minimum of the vapor harmlessly into the atmosphere and produce the least risk to life and property. Make certain to observe the alert messages. They consist of reminders of Dangers, Warnings and Cautions. Other reminders may appear under the heading, Notes. Several components attached to the Multivalve on the fuel tank cannot be removed from the Multivalve until after the fuel tank is removed from the vehicle. This includes the: • • • • fuel supply line fuel return line fuel fill line fuel pump control solenoid The electrical harness attached to the tank is a permanent fixture and cannot be removed in the field. Purging the Fuel Tank A propane fuel tank must be empty of propane before it can be transported by a carrier. Due to the volume of fuel likely to be retained in the fuel tank, releasing the vapor to the atmosphere would be wasteful, unsafe and an extremely slow procedure without special equipment. It is suggested that a local, certified propane handling company be engaged to purge the fuel tank and recapture the fuel as the need requires. Purging System Fuel Lines 1. Disconnect the 4-pin electrical connector at the frame rail on the driver’s side near the fuel tank. Note — This disconnects the power to the fuel pump. 2. Start the engine and let it run until it stalls. Note — This purges the supply and return fuel lines of propane. 3. Turn off the ignition. 4. Disconnect the negative battery cable from the battery. 2/11/2011 Current as of 2-11-2011 42 ROUSH® CleanTech F-250/F-350 Liquid Propane Injection Service Manual Supplement Manual Fuel Shutoff Note — This procedure ensures that no propane leaves the fuel tank during service activity. Warning — Care must be taken while working with liquid propane. All steps must be followed to prevent personal injury and component damage. 1. With the engine turned off, remove the negative battery cable from the battery. 2. Remove the spring clamp and pressure relief hose from the 90-degree elbow on the Multivalve cover. Figure 25 — Spring Clamp and Pressure Relief Hose 3. Remove the 90-degree elbow from the pressure relief valve on the Multivalve cover (turn counter-clockwise) and remove the cover.
