Fuel Delivery System

FUEL SUPPLY COMPONENTS
The fuel supply is stored in the fuel tank. An electric fuel pump, located in the fuel tank with the fuel level sensor sending unit, pumps fuel through an in-line fuel filter to the engine. The pump provides fuel at a pressure greater than is needed by the injectors. The fuel pressure regulator keeps fuel available to the injectors at a regulated pressure. Unused fuel is returned to the fuel tank by a separate line.


FUEL TANK
The fuel storage tank is made of steel and is coated internally with a special corrosion inhibitor and is located in front of the rear wheels. It is held in place by two metal straps attached to the under body of the vehicle.

To help prevent refueling with leaded fuel, the fuel filler neck (1) has a built in restrictor and deflector. The opening in the restrictor will accept only the smaller unleaded gasoline fuel nozzle which must be fully inserted to bypass the deflector.

CAUTION: If a fuel filler cap requires replacement, use only a cap with the same features. Failure to use the correct cap can result in a serious malfunction of the system.

The fuel tank filler neck (1) is equipped with a screw type cap (2). The threaded part of the cap requires several turns counter-clockwise to remove. A built in ratchet type torque limiting device prevents over tightening. To install, turn the cap clockwise until a clicking noise is heard. This signals that the correct torque has been reached and the cap is fully seated.
