Fuel Pump: Description and Operation

PURPOSE
Provides pressurized fuel to the injectors.

LOCATION
The pump and fuel damper assembly is located in the fuel tank.

CONSTRUCTION
It consists of a motor, a vane roller pump, a fuel damper, and a relief valve to prevent system damage from over pressure. The fuel pump shares its mounting cage with the fuel gauge sending unit, and is protected from contaminants by a nylon mesh filtering element. The pump is controlled by a fuel pump relay, which is controlled by the Powertrain Control Module (PCM).
