Install fuel tank in vehicle as described. 7. Lower vehicle. 8. Install a minimum of 38 liters (10 gallons) of fuel. Check for leaks. 9. Turn ignition switch to RUN position for three seconds repeatedly (5 to 10 times) until Multiport Fuel Injection (MFI) Fuel Pressure Gauge 310-012 (T80L-9974-B) or equivalent (depending upon application) shows at least 207 kPa (30 psi). Check for leaks at fittings. 10. Remove Multiport Fuel Injection (MFI) Fuel Pressure Gauge 310-012 (T80L-9974-B) or equivalent (depending upon application), start engine and recheck for leaks.

1. If fuel pump module installation is necessary See: Fuel Pump\Service and Repair\Fuel Pump Module – Installation 2. Secure the fuel tank onto a suitable hydraulic jack with a fuel tank adapter. 3. Raise and position the fuel tank leaving room to make the connections at the top of the fuel tank. 4. Connect the fuel supply line (6) to the fuel pump module. 5. Connect the electrical connector (5) to the fuel pump module. 6. Raise the fuel tank (1) until snug to the body. 7. Install the fuel tank straps (4). 8. Install the strap nuts (5) and tighten to 41 Nm (30 ft. lbs.). 9. Remove the hydraulic jack. 10. Connect the electrical connector to the ESIM switch (4). 11. Connect the quick-connect fitting at the front of the fuel tank (10). 12. Connect the quick-connect fitting (8) at the rear of the fuel tank. 13. Connect the fill hose (7) at the rear of the fuel tank and securely tighten the fill hose retaining clamp (9).

Fuel Charging and Controls The fuel charging and controls system consists of: fuel pressure regulator (9C968) fuel injection supply manifold (9F792) fuel injectors (9F593) fuel shut off valve solenoid (9D278) fuel pressure relief valve (9H321) injection pressure sensor engine fuel temperature sensor fuel charging wiring harness Component Location Fuel Pressure Regulator The fuel pressure regulator is located on the inside of the LH frame rail just forward of the transmission support crossmember. It is part of an assembly that includes the coalescer/filter. The fuel pressure regulator reduces the line pressure from tank pressure 20685 kPa (3000 psi) to line pressure 655 kPa (95 psi). Heating/Defrosting—Natural Gas Vehicle Fuel pressure regulator heating is provided by two 3/8-inch taps from the existing heater supply and return hoses on the RH rear of the engine. Two high-temperature 3/8-inch ID heater hoses (packaged with the front low-pressure fuel line) are used to connect the fuel pressure regulator to the tap points on the engine heater hoses. Refer to the Line — Low Pressure Fuel procedure in Section 310-01B for fuel pressure regulator heater hose replacement. Fuel Pressure Regulator Heater Hoses Fuel Injection Supply Manifold The fuel injection supply manifold delivers high-pressure fuel from the vehicle fuel supply line to the fuel injectors. The fuel injection supply manifold consists of the following: a tubular fuel rail eight fuel injector connectors a fuel pressure relief valve a fuel shut off valve solenoid mounting attachments which locate the fuel injection supply manifold and provide fuel injector retention. a fuel inlet connection which has a push-connect fitting an injection pressure sensor an engine fuel temperature sensor Fuel Injection Supply Manifold Fuel Injectors The natural gas fuel injectors are electro-mechanical devices that meter fuel delivered to the engine. The natural gas fuel injectors are mounted in the lower intake manifold (9424) and are positioned so that their tips direct fuel just ahead of the engine intake valves (6507). The natural gas fuel injector bodies consist of a solenoid and a needle and valve assembly. Natural gas fuel injectors can be identified by an aqua cap on the injector body. Fuel Shutoff Valve Solenoid The fuel shut off valve solenoid seals the upstream fuel pressure from entering the fuel injection supply manifold when the engine is not running. The fuel shut off valve solenoid is open only when it is activated by the solenoid valve (fuel pump) relay. Fuel Pressure Relief Valve The fuel pressure relief valve is located on the fuel injection supply manifold, and is used to relieve fuel system pressure from the fuel delivery system. Injection Pressure Sensor The injection pressure sensor is located on the fuel injection supply manifold, and is used to provide a signal to the powertrain control module (PCM) (12A650) that is proportional to pressure in the fuel injection supply manifold. Engine Fuel Temperature Sensor The engine fuel temperature sensor is located on the fuel injection supply manifold, and is used to provide a signal to the powertrain control module that indicates the temperature of the fuel in the fuel injection supply manifold. Fuel Charging Wiring The fuel charging wiring is a single harness that includes electrical connectors for the fuel injectors, ignition coils and various sensors, valves and senders that monitor all engine functions.
