Product Description

The Walbro GCA758-2 is a complete 255 LPH in-tank fuel pump and installation kit engineered as a direct-fit replacement and performance upgrade for a broad range of iconic 1980s GM performance vehicles. Confirmed fitment covers the 1984-1986 Buick Regal Grand National (3.8L turbo V6), 1985-1991 Chevrolet Camaro (5.0L and 5.7L V8 in all trim levels including Base, Z28, IROC-Z, and RS), 1985-1986 Pontiac Fiero GT, SE, and Sport (2.8L V6), and 1987-1991 Pontiac Firebird Base, Formula, and Trans Am (V8 engines). These applications share a compatible fuel tank and hanger design that allows the GCA758-2 to drop into the factory assembly without modification - simplifying installation significantly compared to universal pump setups that require custom hardware.

At 255 LPH, this pump delivers substantially more fuel volume than OEM pumps in these vehicles, providing meaningful headroom for bolt-on performance modifications, naturally aspirated builds, and mild forced induction upgrades. The proven gerotor pump design that underpins the GCA758-2 is the same fundamental technology trusted by TI Automotive for decades across OEM and high-performance applications - delivering smooth, pulsation-free fuel delivery with low noise and consistent pressure output. The inlet filter included in the kit meets or exceeds OEM filtration specifications, protecting both the new pump and downstream injectors from fuel system contaminants.

As a complete kit, the GCA758-2 includes all components needed for a standard installation: the pump, inlet strainer, submersible fuel hose, wiring pigtail, clamps, and installation instructions. No additional hardware is required for the listed direct-fit applications under normal installation conditions. This pump is designed for gasoline use only and is not compatible with E85 or flex fuel blends. Not CARB legal - not for use in California or other CA-emissions-regulated states. Sold as a complete kit.
