1970-1972 Chevy Chevelle LS EFI Fuel Tank Kit 255 LPH Pump
For LS engine swap projects in a 1970 to 1972 Chevelle that edge toward 550 horsepower this fuel tank kit tackles the threat of pressure loss during heavy acceleration. By pairing a 255 liter per hour Walbro pump with an integrated sending unit and filter the system maintains constant flow under rapid throttle changes within the sealed module. Precision fitment matches the original frame rail spacing on the A Body chassis so no welding or cutting is required for a clean installation. Components made in the USA resist heat soak and vibration for reliable service life and smooth throttle response under all driving loads.
Precision Drop In Fit for 1970 to 1972 Chevelle A Body Rails
The fuel tank kit has been engineered to match the exact frame rail spacing and strap locations of 1970 to 1972 Chevelle A Body chassis, delivering a true drop in installation without requiring any cutting or welding. By replicating the factory undercarriage geometry, the assembly preserves original ground clearance and maintains the routing of brake and suspension lines. Installers save substantial time with minimal trial and error while protecting welds and frame integrity. The design process included careful measurement of rail curvature and strap tension, ensuring a secure hold even under spirited driving. This precise dimensional control also supports consistent tank position that prevents clearance issues under heavy road loads.
Engineered In Tank Fuel Delivery for LS Engine Swaps
At the core of the kit is a 255 liter per hour Walbro fuel pump calibrated to support LS engines producing up to 550 horsepower without risk of suction cavitation or pressure drop during wide open throttle events. The integrated module houses pump, fuel sending unit and internal filter in a sealed enclosure that resists vapor lock by stabilizing pressure above the fuel level. An internal vent filter maintains a consistent vapor barrier and prevents air intrusion under rapid throttle transitions. By combining high volume flow with precise calibration, the system sustains a stable air fuel ratio across the entire rpm range, enhancing throttle response and drivability in both street and track applications. Precision gaskets and hardware complete the sealed assembly, eliminating leaks and ensuring uninterrupted performance.
United States Fabrication Ensuring Durability in Heat and Vibration
Every component in this fuel tank kit is made in the United States to meet stringent quality control standards and material specifications required for high demand engine swaps. From the pump module to the tank straps, filler neck and gaskets, domestic sourcing allows for full traceability and consistency across production batches. These parts are engineered to resist heat soak common in high output applications as well as vibration and road shock found in vintage chassis. The use of precision machined hardware and robust mounting straps ensures long term fitment and reliable service life, even under repeated thermal cycling and aggressive driving conditions. This commitment to local fabrication also delivers faster lead times for replacement parts when maintenance is required.
