Fuel Tank: Description and Operation

The fuel system consists of:
^ the fuel tank.
^ the fuel tank filler pipe which contains a restrictor plate to permit only unleaded fuel to be pumped into the fuel tank.
^ an 1/8 turn type fuel tank filler cap.
^ a fuel filter providing filtration to protect the fuel injectors.
^ an electronic returnless fuel system.
^ a single fuel line accommodating the returnless system.
^ a fuel transfer pump which sends the fuel in the left fuel tank lobe to the fuel delivery module in the right hand lobe and contains a fuel level sensor.
- It has a check valve which maintains system pressure after the pump is shut off.
- It is sealed with a gasket.
^ a fuel delivery module which provides pressurized fuel to the engine and contains:
- a fuel level sensor.
- an inlet filter.
- The mounting ring is sealed with a gasket.

The fuel pump is controlled by the Powertrain Control Module (PCM) which energizes the fuel pump relay. Electrical power to the pump is provided through the Inertia Fuel Shutoff (IFS) switch, which is located in the passenger compartment behind the lower A-pillar trim panel.
