This OE-style 350 LPH EFI fuel pump module is built as a direct replacement for the factory pickup and sending unit in 1978-1987 GM G-Body fuel tanks, so no custom EFI tank is needed. The factory fuel line can be retained; connect the pump module outlet to the vehicle's hard line with EFI-rated fuel hose and hose clamps.

Specifications:

FAQ

What vehicles does the Holley 12-335 fuel pump module fit?

It's a direct-fit replacement for 1978-1987 GM G-Body vehicles (Chevrolet El Camino, Malibu, Monte Carlo, and related G-Body models), designed to fit inside the factory fuel tank in place of the stock pickup and sending unit.

Do I need a new fuel tank to install this module?

No. The module is designed as a direct replacement for the factory pickup and sending unit, so the factory fuel tank and fuel line can be retained.

Holley recommends EFI-rated fuel hose and hose clamps, such as those in the Earl's Vapor Guard line, to connect the pump module outlet to the vehicle's factory hard line.
