Sparta PN8027 Mechanical Fuel Pump

Mechanical Fuel Pump for Classic GM Applications

The Sparta PN8027 mechanical fuel pump is a standard replacement for higher-mileage and earlier model gas vehicles that use a mechanical fuel delivery system. Built with an aluminum housing, threaded outlet, and hose bead inlet, it is a direct-service part for classic Chevrolet, GMC, Buick, Oldsmobile, and Pontiac applications.

Sparta is distributed by Delphi, an OE fuel system supplier, and this pump is built for the fit and performance expectations of older vehicles. The PN8027 is a practical choice for restoring steady fuel delivery on carbureted engines in vehicles such as the Chevrolet C10, Camaro, and Pontiac Firebird.
