Lock Ring Fuel Pump Module GM 4.75in

The Lock Ring Fuel Pump Module GM 4.75in is a critical OEM-replacement mounting ring engineered for General Motors fuel pump assemblies. This twist-lock retaining ring secures the fuel pump module inside the fuel tank, ensuring reliable fuel delivery and system integrity across demanding driving conditions. Technicians and DIY rebuilders rely on this component when servicing fuel pump modules on GM vehicles or performing fuel system diagnostics and repairs.

Manufactured from durable steel and finished in black paint, the Lock Ring Fuel Pump Module GM 4.75in features a 4.25-inch inner diameter with a 4.75-inch mounting hole specification that locks directly onto the fuel pump sender assembly. The twist-lock design eliminates the need for additional fasteners, allowing quick hand-tightening and tool-free removal during maintenance intervals. Steel construction resists corrosion and vibration—essential qualities in the harsh fuel tank environment where moisture and temperature fluctuations are constant challenges.

This ring is ideal for technicians performing fuel pump replacement, fuel gauge sender repairs, or complete fuel system overhauls on compatible GM platforms. Proper installation ensures a watertight seal, prevents fuel leakage, and maintains system pressure stability. Always verify OEM compatibility by cross-referencing your vehicle's fuel pump module specifications before purchase to guarantee correct fitment and safe operation.
