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 may appear from time to time in appropriate places in this manual. Ensure that all personnel read and adhere to these alert messages. 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. 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. Page 2 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. 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. 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. Technicians working with, or around, fuel systems should be properly trained to utilize extreme care and caution at all times. Failure to exercise extreme caution and care may lead to serious accidents which can result in property damage, personal injury and/or death. Liquid propane is cold. The temperature of propane in its liquid state at atmospheric pressure 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. INTRODUCTION 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. 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. Paragraph 11.2 specifies that each person engaged in installing, repairing, filling or otherwise servicing an LP-Gas engine fuel system shall be trained.

Action Refer to the Secondary Tank – Fuel Will Not Transfer Troubleshooting. Page 19 TROUBLESHOOTING Secondary Tank – Fuel Will Not Transfer F-650 vehicles can be equipped with a unique ROUSH CleanTech liquid propane autogas storage system which includes two fuel tanks. The system operates as if it were just one large tank. A few key points about the system: • The engine is always running from the driver's side tank. All fuel to the engine, and the excess fuel returning to the tank, is only connected to this tank. • The passenger's side tank is used to store extra fuel only. When the driver's side tank fuel level drops, the system will activate fuel pumps in passenger's side tank to transfer fuel automatically. • Both tanks are filled at the same time from the single fuel filler located on the driver's side. There is a ball valve on the fill line for the right-hand tank, which is used for periodic inspections only. It should always be open during normal operation in order to use the full system capacity. The ROUSH CleanTech control system reads the usable fuel level in each tank and adds them together to provide a single reading for the instrument cluster. However, if the system detects a failure in the fuel transfer system which may interfere with the ability to transfer fuel, it will provide a reading based on the driver's side tank only. This ensures that the driver is warned before the vehicle runs out of fuel. If this occurs, the vehicle is fully usable, but should be serviced in order to restore full function and use of the full system fuel capacity. The fuel transfer line from the passenger's side tank is connected to a dedicated overfill prevention device (OPD) on the driver's side tank. This is a safety device which ensures that even if there is a fault in the control system, it is not possible for the driver's side tank to overfill during transfers. Page 20 TROUBLESHOOTING DIAGNOSTIC TESTS AND PROCEDURES General Information Expected Fuel Tank Pressure — On a tank at ambient temperature conditions, the following pressures can be expected: Pressure (psi) Measuring Fuel Rail and Fuel Tank Pressure Measuring Fuel Tank Pressure — Fuel tank pressure can be measured two ways: Refer to Tools and Equipment, Special Tools in the 2012 Ford E-150/250/350/450 or 2013 F-250/350 Liquid Propane Autogas Fuel System Service Manual Supplement for more information regarding the tools required. Method 1 — Install a 0–500 psi (0–3447 kPa) fuel pressure gauge on the bleeder valve at the tank, or to the remote bleeder valve location. Open the valve to monitor the fuel tank pressure. Record the value. Method 2 — If a 0–500 psi (0–3447 kPa) fuel pressure gauge is not available, fuel rail pressure can be used to infer fuel tank pressure. Refer to Method 1 of Measuring Fuel Rail Pressure. Monitor fuel rail pressure with the engine running. Turn the engine off and continue to monitor fuel rail pressure. When the pressure has stabilized, record the value as fuel tank pressure. Temperature (°F) Min.

Method 1 — Using the OBD-II scan tool, read the fuel rail pressure PID. If using the Ford IDS tool, it will be necessary to select the tool box tab, then select Powertrain near bottom of selection, OBD Test Modes, Mode 1 Powertrain Data. Then locate and select FRP (pressure) from PID selection table. Method 2 — Empty the fuel rails and fuel lines. Refer to the Fuel Line Purging Procedure in the 2012 Ford E-150/250/350/450 or 2013 F-250/350 Liquid Propane Autogas Fuel System Service Manual Supplement for more information. Using the Jiffy-Tite disconnect tool, disconnect the fuel supply line at the rear of the RH fuel rail. Install the ROUSH service port adapter between the fuel line and the fuel rail. Attach 0–500 psi (0–3447 kPa) fuel pressure gauge to the service port on the adapter. Record the value. 85 131 141 151 90 142 152 162 95 153 163 173 100 165 175 185 105 178 188 198 110 191 201 211 115 205 215 225 120 219 229 239 On vehicles that have been operated for extended periods of time, the tank (fuel) can be much warmer and so higher pressures are to be expected. Expected Fuel Rail Pressure — Under normal operating conditions, the fuel pump has two operating speeds. The pump operates in low speed mode at idle and during moderate fuel flow/part throttle driving. Once a fuel demand threshold is met, typically during wide open throttle (WOT) operation, the pump is switched to high speed. The pump is also operated at high speed during the pre-start flush sequence. Page 21 TROUBLESHOOTING The fuel pressure controls are designed to keep the rails at a certain pressure over tank pressure, therefore, it is important to measure tank pressure prior to collecting fuel rail pressure data. For example, if the fuel tank is at 150 psi (1034 kPa) and pressure in the rail is measured at 200 psi (1379 kPa), the rail is running at 50 psi (345 kPa) over tank. Condition Pump Speed Pressure Over Tank Engine Off Off <10 Idle Low >30 Part Throttle Low <25 Part Throttle High >25 WOT High >25 Under extreme operating conditions, there is a third pump mode. In the event that the fuel system has degraded and the sensor detects vapor, or if the fuel rail pressure is approaching the limit of the fuel system, the pump runs in a variable speed mode, controlling to a target pressure. In this mode there is no predicted rise over tank pressure. The fuel pump will adjust the pressure to maintain a required operating pressure. This condition will likely result in a P116E or P0148 code. No Fill Step Procedure Action 1 Inspect vehicle to check for kinked fill lines. Are fill lines kinked? Yes — Replaced kinked fill lines.

If OK, replace sensor. 12 Refer to the appropriate Ford Powertrain Control/Emissions Diagnosis Service Manual at www.motorcraft.com. — Excess Flow Valve Check The excess flow valve (XFV) is designed to restrict fuel exiting the tank if the pump is energized while the fuel lines are not connected to the fuel tank. Under normal circumstances, the XFV should not trip. The XFV will reset itself after the fuel pumps have been off for about one minute. If the fuel lines have not been serviced recently and the problem persists, there may be a leak in the supply side fuel line. If the problem is only present after the vehicle has been sitting for a length of time, but not present during a short soak, or there is a propane odor when the vehicle is running, refer to the Fuel Line Leak Detection procedure. It is common to trip the XFV after the fuel lines have been serviced and contain no pressure. If the XFV trips, turn the vehicle off, wait one minute, and restart. This may take more than one attempt. Step 1 Procedure Verify fuel supply line pressure prior to cranking engine. a. b. Read fuel rail pressure and tank pressure. Energize bleed solenoid until rail pressure is at least 50 psi (345 kPa) below tank pressure. If rail is bled, skip to Step D. c. Let pressure stabilize for 1 minute. d. Open the supply solenoid. e.

Page 31 TROUBLESHOOTING Maximum Pressure Check The LPA system operates over a wide range of pressures depending on ambient temperature, driving mode, etc. When the vehicle is subjected to a severe drive cycle in high ambient temperatures, the fuel rail pressure can rise to the limit of the injectors capabilities. This limit is a function of injector voltage and fuel rail pressure. The PCM protects for this condition by reducing the fuel pump speed when the condition is sensed, however, there still may be drive concerns. When the PCM starts controlling the fuel pump a P116E code is set. While this Step 1 condition can occur in a normally functioning vehicle, it can also be exacerbated by several factors. If the fuel tank was not properly bled during the first fill, trapped air in the vapor space can increase tank pressure. In this condition there is often only a faint smell of propane when the bleeder valve is opened. The tank should be vented until there is a strong propane odor coming from the bleeder valve. The tank pressure should be confirmed against the expected pressure. Allow the fuel tank to cool to ambient temperature before performing the following procedure. Procedure Measure tank pressure and tank surface temperature. Is tank pressure more than 15 psi (103 kPa) over expected tank pressure?

If OK, replace sensor. 8 Refer to the appropriate Ford Powertrain Control/Emissions Diagnosis Service Manual at www.motorcraft.com. — Page 35 TROUBLESHOOTING Fuel Level Indication Check The ROUSH CleanTech fuel level indication system differs from the gasoline system as the fuel level sender is not wired directly to the instrument cluster. Instead, the fuel level sender is wired to the SRM, which reads the fuel level and transmits the signal to the PCM via the CAN bus, and to the FLIM, which in turn simulates the resistance the instrument cluster expects to see for a given fuel level. The gauge on the sending unit must not be used for any diagnostics. The gauge is not accurate. Only resistance or voltage outputs should be used for diagnostic purposes. Symptom Cause/Action to be taken Fuel gauge does not move on a partial fill This behavior is not uncommon. The fuel level sender may not move far enough to trigger movement on the gauge if only a small amount of fuel is added to the tank. Once driven, the gauge may move to reflect the fill. Malfunction Indicator Lamp (MIL) There is a circuit fault that has been identified by the PCM. Initially follow the Ford Powertrain Control/Emissions Diagnosis Service Manual, whenever a circuit check is called for, refer to the Fuel Level Interface Module Electrical Test procedure. Gauge points below E This is an indication of an error state. Initially follow the Ford Powertrain Control/Emissions Diagnosis Service Manual, whenever a circuit check is called for, refer to the Fuel Level Interface Module Electrical Test procedure. Doesn’t read full after a fill This could be the result of either a fuel level sender fault or an OPD valve triggering prematurely. Refer to fill issues and the Fuel Level Sender Electrical Check procedure for more information.
