Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Primary Fuel Pump Module
The primary fuel pump module is mounted on the top of the fuel tank and contains the following components:
- Mounting flange
- Electric fuel pump
- Venturi jet pump (AWD)
- Fuel pump reservoir
- Inlet strainer
- Fuel pressure regulator
- Fuel level sending unit
- Fuel filter
If equipped with All Wheel Drive (AWD), the primary fuel pump module will also contain a venturi jet pump. The primary fuel pump module is joined to the secondary fuel pump module (AWD) by an internal nylon fuel transfer line equipped with quick-connect fittings (4).
The fuel level sending unit (3) is the only serviceable component of the primary fuel pump module. If the electric fuel pump, fuel pressure regulator or fuel filter requires service, the primary fuel pump module must be replaced as an assembly.
