Carter M6954 Mechanical Fuel Pump

Carter M6954 Mechanical Fuel Pump Overview

The Carter M6954 is a mechanical fuel pump built for OE-style fit, form, and function on select Chevrolet and GMC vans and trucks. It uses a hose inlet, threaded outlet, and a single outlet configuration to support the fuel delivery setup specified for covered applications.

With a gasket or seal included and a mechanical pump design, this Carter fuel pump is a direct replacement option for vehicles that require a short housing, 3-line configuration. It is listed for Chevrolet G10, G20, and G30, as well as GMC G15, G25, G35, G1500, G2500, and G3500 applications.

Detailed Product Description

Carter M6954 is engineered for fuel delivery service on select 1977-1981 Chevrolet G10, G20, and G30 models, plus 1977-1981 GMC G15, G25, G35, G1500, G2500, and G3500 applications. Fitment notes call for short housing mechanical fuel pump configurations with 3-line layouts, including GMC applications with air conditioning where specified. The threaded outlet and hose inlet match the listed vehicle requirements, while the included gasket or seal supports proper sealing during replacement.

This part cross-references Delphi MF0114 for the same application. If you are replacing a worn mechanical fuel pump on a Chevrolet G10 or GMC G3500, M6954 provides a cataloged replacement path with the correct configuration details for the covered vehicles.

Common Problems This Part Can Address

• Hard starting caused by weak fuel delivery
• Fuel starvation under normal engine operation
• Pressure loss from a worn mechanical pump
• Fuel seepage at the pump mounting surface
• Replacement needs on short housing, 3-line fuel pump setups

Installation Notes and Tips

Verify the vehicle’s pump style, housing length, inlet type, outlet type, and line routing before installation. This pump uses a threaded outlet and hose inlet, so confirm the fuel line connections match the original setup on your Chevrolet or GMC application. Clean the mounting surface thoroughly and install the included gasket or seal to help achieve a proper seal.

Because fitment is specific to short housing mechanical fuel pump applications, compare the original pump to the Carter M6954 before installation on Chevrolet G10, G20, G30, GMC G15, G25, G35, G1500, G2500, or G3500 models.
