Fuel Pump

The fuel pump is a high pressure rollervane type, electric pump, which mounts in the fuel tank. Fuel is pumped, at a specified flow and pressure from the fuel pump, through the in-line filter to the pressure regulator in the fuel injection unit. Excess fuel is returned to the fuel tank through the fuel return line.

The fuel pump attaches to the fuel sender assembly. A fuel strainer attaches to the fuel pump inlet line. The strainer prevents dirt particles from entering the fuel line and tends to separate water from the fuel. A ceramic resistor card for the fuel level sensor is also attached to the outside of the sender assembly. The function of the ceramic resistor card is to vary the resistance, depending on the position of the float and to send a signal to the fuel gage via the BCM. The modular fuel sender assembly is serviced as a complete assembly. The only serviceable components on the modular unit are the strainer, fuel level sensor, and the OBD II fuel tank pressure sensor.
