F-150 Heritage Pick-up
1.Fuel rail sensors -An injection pressure sensor and an engine fuel
temperature sensor provide engine fuel information to the powertrain
control module.
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.Underbody 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 and removes impurities from the gas.
11.Low pressure fuel line -Supplies natural gas to the injectors.
12.AFV module -Contains the unique powertrain electronics that are
required for an NGV.
Crown Victoria
1.NGV module -Provides power for the fuel injectors. Also, drives the
fuel gauge using fuel tank pressure and temperature sensors.

2.Isolation solenoid valve -Blocks flow from the injection manifold
when the engine is off.
3.Engine -Is a modified 4.6L engine with Sequential Electronic Fuel
Injection (SEFI) and increased compression ratio.
4.Engine coolant lines -Provide required heat to high pressure
regulator.
5.Powertrain control module -Required for NGV application.
6.Sealed vent box -Vented to underbody. Dispenses natural gas vapor
to atmosphere if vapor becomes present.
7.Tank pressure sensor -Fuel tank pressure sensor located in this
tank’s solenoid valve is used for fuel indication.
8.Solenoid tank valves -One solenoid per tank. Internal valves with
shut-off solenoids wired into inertia circuit for crash protection.
9.Two fuel tanks -Located in the trunk. On taxi or police vehicles, an
extended range fuel system is available which includes one additional NG
fuel tank mounted in the trunk (total of three).
10.Fueling point -Fueling receptacle is conveniently located with the
fuel door. Same location as gasoline fueled vehicles.
11.Tank shield-Protective shield able to prevent damage to the fuel
tanks caused by trunk cargo.
12.Tank temperature sensors -One each in set of tanks (solenoid
valves) used for fuel indication.
13.Optional fuel tank -A fiber-wrapped steel fuel tank (total of three
tanks in the trunk). Also has a sealed vent box which vents to the
underbody. Dispenses natural gas vapor to the atmosphere if vapor is
present.
14.Two fuel tanks -Located underbody to facilitate fuel system design.
15.Stone and heat shield -Protective shield able to prevent damage to
the fuel tanks caused by road debris or other road hazards.
16.High pressure fuel lines -Delivers high pressure fuel to the
pressure regulator.
17.Pressure regulator and coalescent fuel filter assembly -
Reduces the fuel pressure to the fuel injector.
18.Low pressure fuel lines -Supplies natural gas to the engine.
19.Fuel rail sensors -One injection pressure sensor and one engine
fuel temperature sensor provide engine fuel information to the PCM.

The purpose of the inspection is to check for exterior damage to the
tank which would shorten its usable life span. This inspection should
only be done by qualified NGV Ford service technicians.
The expiration date for the tank replacement is stated on each tank label
See instructions on fuel container for inspection and service life.
Coalescent fuel filter assembly
Your vehicle is equipped with a coalescent fuel filter assembly. Its
primary function is to remove contaminants; oil and water carryover
moisture from the fuel and trap it in the filter bowl.
The coalescent filter bowl should be drained every 48,000 kilometers
(30,000 miles). Perform fuel system depressurization procedure (outlined
in Service Manual) before disassembling the filter to avoid fuel pressure
regulator damage. The filter element (FG-985) and housing O-ring seal
should also be replaced as specified in the Scheduled Maintenence
Guide.
Spark plugs
Replace spark plugs every 96,000 kilometers (60,000 miles) on E-Series
and F-150 Heritage models and every 60,000 km (36,000 miles) on
Crown Victoria models. Use recommended nickel-plated platinum spark
plugs with the Motorcraft part number AWSF-22FM1 (or equivalent) on
E-Series and F-150 Heritage models and spark plugs with the Motorcraft
part number AWSF-22FM (or equivalent) on Crown Victoria models.
