WARNING: Do not modify the system configuration or components or install components with parts not specially designed for use with natural gas. Ford Motor Company has specially designed the materials, components and system configuration for the Crown Victoria natural gas vehicles, and each particular system is precisely calibrated for efficient operation. The use of different parts or materials can produce an untested configuration that could result in fire or personal injury or cause engine damage.
CAUTION: It is important that your natural gas vehicle be correctly maintained by Ford natural gas trained personnel. If a problem occurs, it is important that correctly trained personnel diagnose the cause. If the problem relates to the fuel system, correct new part installation is imperative to keep your vehicle operating at normal performance. Natural gas components and gasoline fuel components are not interchangeable. If your vehicle is not serviced in accordance with natural gas-fueled vehicle procedures, damage can occur and your warranty can be invalidated.
NOTE: All standard production components and systems receive routine service under base warranty procedures.
Natural gas labels are affixed to the inside of the fuel filler door.
Fuel Fill Valve
The fuel fill valve is located behind the fuel filler door inside the fuel filler compartment. The fuel fill valve consists of a receptacle for a fueling connection, a check valve, and a particulate filter.
Fuel Lines
The fuel filler, fuel tanks and fuel pressure regulator assembly are connected by stainless steel braided flexible lines with oiled O-ring face seal fittings.
Coalescer/Filter
The coalescer/filter assembly filters, separates and stores contamination or moisture found in the fuel system, preventing moisture from entering the engine. The coalescer/filter assembly should be drained of moisture on a regular basis, such as each engine oil change.
Fuel Pressure Regulator
The fuel pressure regulator is located on the inside of the LH frame rail forward of the of the LH rear tire. It is part of an assembly that includes the coalescer/filter. The fuel pressure regulator reduces the line pressure from tank pressure, 24,821.1 kPa (3,500 psi), to line pressure, 855 kPa (125 psi).
Fuel Tanks and Solenoid Valves
The fuel tanks are constructed of fiberglass-wrapped steel, mounted in three insulated racks with two tanks per rack. Two racks with 267 mm (10.68 inch) diameter tanks are located in the luggage compartment, one above the rear axle area (upper rack), and the other (rear rack) to the rear. The lower rack has two 218.75 mm (8.75 inch) diameter tanks and is located in the production gasoline fuel tank area. Each tank has an internal, normally closed solenoid shutoff valve wired to the inertia fuel shutoff circuit to isolate the fuel tanks in the event of a collision.
Fuel Tank Racks
WARNING: Do not modify the system configuration or components or install components with parts not specially designed for use with natural gas. Ford Motor Company has specially designed the materials, components and system configuration for the Crown Victoria natural gas vehicles, and each particular system is precisely calibrated for efficient operation. The use of different parts or materials can produce an untested configuration that could result in fire or personal injury or cause engine damage.
The fuel tank racks have a rubber insulator to protect the fuel tanks from wear due to vibration. The fuel tank racks are bolted to the vehicle by retainer brackets and supports welded to the body.
