Lock Ring Fuel Pump Module GM 6in

The Lock Ring Fuel Pump Module GM 6in is a precision fuel delivery component engineered for General Motors applications requiring reliable in-tank pump assembly integration. This module serves as the critical interface between the fuel tank and the engine's fuel system, delivering consistent pressure and volume to modern GM fuel injection systems. Built for fleet mechanics, tactical equipment specialists, and automotive professionals who demand OEM-grade performance, this lock ring assembly ensures secure module positioning and eliminates fuel leaks at the tank interface.

The 6-inch design accommodates standard GM fuel tank openings with precision tolerances that guarantee a tight, vibration-resistant seal under operating pressure. The lock ring mechanism employs a proven ratcheting system that prevents accidental loosening during vehicle operation, thermal cycling, or rough terrain navigation—critical for both civilian fleet vehicles and tactical transport platforms. Constructed from durable materials engineered to withstand fuel system pressures and temperature fluctuations, this module integrates seamlessly with OEM and aftermarket fuel pump assemblies commonly found in GM light-duty and medium-duty trucks.

Mechanics and technicians working on GM fuel system repairs benefit from the straightforward installation design and reliable holding force this lock ring provides. The compact 0.745 lb profile and 7.8 x 1.75 x 8.2 inch footprint allow for easy handling during fuel tank service or pump replacement procedures. Compatibility spans multiple GM model years and platforms; verify tank opening diameter and pump module specifications against your vehicle's service manual before ordering. This component is essential for any comprehensive fuel system rebuild or maintenance operation on General Motors vehicles.
