Delphi MF0024 Mechanical Fuel Pump

Mechanical Fuel Pump for Classic GM Applications

The Delphi MF0024 is a standard replacement mechanical fuel pump for gasoline applications that use a 2-line fuel pump setup. Built from Delphi’s OE heritage and application knowledge, it is suited for classic Buick, Oldsmobile, and Pontiac vehicles that need consistent fuel delivery at 5 psi.

With a threaded outlet, hose-bead inlet, included gasket, and a 30 average flow rating, this pump is built for direct service on older carbureted fuel systems. It is a practical choice for restoring fuel pressure on vehicles such as the Buick LeSabre, Oldsmobile Cutlass, and Pontiac Firebird.

Detailed Description

Delphi MF0024 is engineered for older fuel systems that rely on a mechanical pump mounted on the engine. It draws gasoline through a hose-bead inlet and delivers fuel through a single threaded outlet, making it a straightforward replacement for many GM rear-wheel-drive platforms. This part cross-references Carter M6108 for the same application. The MF0024 is listed for a broad range of 1970-1984 Buick, Oldsmobile, and Pontiac models, including Buick LeSabre, Buick Regal, Oldsmobile Delta 88, Oldsmobile Cutlass, Oldsmobile 98, and Pontiac Firebird.
