1970-1972 Chevy Chevelle A-Body LS EFI Fuel Tank Kit with 255 LPH Pump
When fitting an LS motor into your 1970-1972 Chevelle A-Body chassis, consistent fuel pressure is critical under full throttle, and this EFI fuel tank kit with a 255 LPH Walbro pump addresses that challenge directly. Precision matched to the stock frame rail spacing, the modular assembly drops in without any cutting or welding and maintains original ground clearance along brake and suspension lines. Built in the USA from quality materials, the sealed pump module combines tank, sending unit and filter to stabilize flow, prevent vapor lock and support LS setups up to 550 hp.
Sealed Pump Module Ensures Vapor Lock Prevention
At the heart of this kit lies the sealed pump module which integrates the 255 LPH Walbro pump, fuel sending unit, and internal filter within a single enclosure. This design creates a stable pressure environment by keeping fuel continuously pressurized above the intake line. As a result, the system eliminates vapor pockets that can lead to engine hesitation or lean spikes during hard acceleration. The internal vent filter further maintains a consistent barrier against air intrusion, ensuring smooth throttle response even at wide open throttle. Precision gaskets and mounting hardware complete the assembly to deliver leak free operation under all driving conditions.
Precision Frame Rail Alignment for Effortless Installation
Engineered to match the exact spacing of 1970 to 1972 Chevelle A Body frame rails, the fuel tank kit offers a true drop in fit that removes the need for cutting or welding. By mirroring the original undercarriage geometry, the assembly preserves factory ground clearance and maintains the routing paths for brake and suspension lines. Installers benefit from reduced setup time and minimal trial and error, securing the tank using the provided straps and hardware without risking damage to the chassis. This dimension control also ensures the tank remains stable beneath the vehicle, preventing interference with road irregularities or spirited driving loads.
Quality USA Fabrication for Heat and Vibration Resistance
All components in this kit are manufactured in the United States under strict quality standards to guarantee consistent performance. The fuel tank, filler neck, straps, and gaskets are sourced domestically to allow full material traceability and batch verification. Domestic fabrication techniques focus on resisting heat soak common in high output engines as well as withstanding vibration and shocks characteristic of vintage chassis dynamics. Robust mounting hardware and reinforced module construction ensure that the system endures repeated thermal cycling and aggressive cornering without failure. This commitment to local production also means quicker access to replacement parts and upgrades.
Built for consistent pressure and vapor lock prevention, this kit ensures reliable operation under demanding conditions. For a larger capacity fuel pump kit at 400 LPH see our 1970-1972 Chevelle EFI Fuel Tank Kit - 400 LPH Pump.
