Fuel Pump Assembly

The fuel pump assembly is mounted inside the fuel tank and contains the following components:

• Mounting flange
• Electric fuel pump
• Fuel pump reservoir
• Inlet strainer
• Fuel pressure regulator
• Fuel level sending unit
• Fuel filter

The FPCM controls the fuel pump using a High Side Driver (HSD) PWM control circuit. The fuel pump ground circuit is also connected to the FPCM. The electric fuel pump is located within the fuel pump module assembly. The electric fuel pump is a positive displacement, immersible pump with a permanent magnet electric motor capable of creating 860 kPa (125 psi) of operating pressure. The fuel pressure regulator's operating range is 400 kPa (58 psi) to 552 kPa (80 psi). The fuel level sending unit is the only serviceable component of the primary fuel pump assembly. If the electric fuel pump, fuel pressure regulator or fuel filter requires service, the primary fuel pump assembly must be replaced.
