The turbine-style design, in-tank layout, and included harness and seals support a direct-service replacement for many GM rear-wheel-drive and front-wheel-drive platforms, including Chevrolet S10, Chevrolet Blazer, GMC Jimmy, and Pontiac Firebird applications. This part cross-references Airtex Fuel Pumps (e.g., E2485, E3240) for the same application.
