LS and LT EFI Fuel Tank Kit for 1978-1981 Camaro/Firebird F-Body
A single hesitation under full throttle can derail an LS or LT swap, so the 1978 to 1981 Camaro / 1979 to 1981 Firebird EFI Fuel Tank Kit delivers consistent pressure through every throttle tip in. Its precision design matches factory frame rails on 1978 to 1981 Chevy Camaro and 1979 to 1981 Pontiac Firebird models, eliminating trimming or welding while preserving chassis clearance. Equipped with a 400 LPH Walbro pump rated for builds above 550 hp, this tank kit includes a sending unit, straps, filler neck and vent filter to prevent fuel starvation during hard acceleration. Easy to follow instructions walk installers through pressure management steps, ensuring steady fuel flow in aggressive street and track applications.
Precision Fit Design for 1978 to 1981 Camaro and Firebird Chassis
The fuel tank kit's shell and mounting bracket geometry are engineered to align precisely with the factory frame rails on 1978 to 1981 Chevrolet Camaro and 1979 to 1981 Pontiac Firebird models. By matching existing holes and attachment points, the system eliminates cutting or welding, preserving the integrity of the frame and avoiding costly modifications. This precision fit also ensures that the in tank assembly sits flush against the original tank opening, maintaining original ground clearance and preventing rubbing on suspension components. Installers experience reduced trial fitting and can move directly to plumbing and wiring, streamlining the swap process for LS or LT engine platforms.
400 LPH Walbro Pump Supporting Builds Above 550 hp
At the heart of this kit is a 400 LPH Walbro pump selected for its consistency under high demand and rapid throttle changes. The internal impeller and flow path design maintain steady pressure during hard acceleration, preventing lean conditions that cause hesitation or engine knock. This level of fuel delivery meets the needs of forced induction and high compression LS and LT powerplants, ensuring reliable fuel supply from idle through wide open throttle. Proper pump performance also reduces the risk of vapor lock in hot operating environments and safeguards calibrated engine management settings.
Integrated Components for Streamlined EFI System Assembly
This comprehensive kit brings together the pump module, sending unit, filler neck, vent filter, straps, gaskets and all necessary hardware for a complete fuel supply solution. Each element is designed for compatibility and ease of assembly, with the vent filter managing tank pressure and preventing vapor buildup during spirited driving. The filler neck fits the original body opening without alteration, and the straps secure the tank firmly under dynamic loads. Clear, easy to follow instructions guide installers through fuel line routing and pressure adjustment, reducing installation time and minimizing the chance of leaks or missteps.
