Servicing your vehicle 2. Isolation solenoid valve-Blocks flow from supply line to injection manifold when the engine is off. 3. Engine-A modified 5.4L gasoline engine with Sequential Electronic Fuel Injection (SEFI), an improved valvetrain and a high compression ratio. 4. Powertrain control module-Uniquely calibrated for NGV application. 5. Internal tank valve-One electronically actuated, normally closed solenoid valve is located in each fuel tank. The valve is wired into the vehicle's inertia switch. If the engine cranks but does not start after a collision, the fuel solenoid valve inertia switch may have been activated. The inertia switch is a device intended to close the fuel solenoid valve when your vehicle has been involved in a substantial jolt. 6. Standard fuel tanks-Two steel fuel tanks located in the bed of the truck. 6b. In-bed tank cover-Cover to prevent damage to the fuel tanks. Protective shield to prevent damage to the fuel tank caused by road debris or other road hazards. Do not sit, stand or place heavy loads on the fuel tank cover. 7. Stone shield-Protective shield to prevent damage to the fuel tank caused by road debris or other road hazards. 8. Optional fuel tank-A steel fuel tank located underbody. 9. High pressure fuel lines-Delivers high pressure fuel to the fuel tanks and fuel pressure regulator. 10. Fuel pressure regulator/Coalescent fuel filter-Reduces fuel pressure to 95 psi and removes impurities from the gas. 11. Low pressure fuel line-Supplies 95 psi of natural gas to the injectors. 12. NGV module-Contains the unique powertrain electronics that are required for an NGV. 8
