The fuel pump module is located in the right of the fuel tank. The fuel pump module is sealed to the fuel tank with an O-ring seal and secured with a flange retaining ring.
The top flange of the fuel pump module assembly provides the internal and external interface for the fuel tank electrical and fuel connections. The flange is formed with fuel level and LP fuel pump wiring harness connector. The connectors on the fuel pump module are for the fuel level sensors and the LP fuel pump.
The lower part of the fuel pump module forms the fuel swirl pot, and provides the location for the LP fuel pump. The swirl pot provides a constant reservoir of fuel to deliver fuel to the engine.
The LP fuel pump makes sure that sufficient fuel is delivered to the engine's HP fuel pumps. The suction pipe draws fuel from the left (passive) of the fuel tank into the swirl pot. Surplus fuel entering the fuel swirl pot overflows into the usable right of the fuel tank.
Fuel Fired Booster Heater (if equipped)
For cold climate market vehicles that are equipped with a FFBH and an FFBH fuel pump. The fuel pump module has a separate pipe connection for a FFBH fuel line, that connects to a FFBH fuel pump mounted on the exterior right of the fuel tank. The FFBH fuel line connection is installed with a sealed suction pipe which draws fuel from the swirl pot. An additional fuel line connects the FFBH fuel pump to the FFBH fuel inlet.
