LS EFI Fuel Tank Kit for 1970-1972 Chevy Chevelle A-Body
Installing a high-output LS motor in a 1970-1972 Chevy Chevelle A-Body often exposes limitations in the factory fuel delivery system, and this EFI fuel tank kit equipped with a 255 LPH Walbro pump ensures unwavering fuel supply for setups up to 550 hp. The modular assembly aligns precisely with original frame rail spacing and drops in without cutting or welding, maintaining factory ground clearance around brake and suspension lines. Built in the USA from corrosion resistant materials, the sealed pump module houses the pump, sending unit and internal filter in a single enclosure to keep fuel continuously pressurized above the intake line and prevent vapor lock. Installers benefit from complete hardware and precision gaskets that cut trial and error and deliver leak free operation under spirited street or track conditions.
Precision Frame Rail Alignment for Direct Fit Installation
The fuel tank kit is engineered with exact frame rail spacing for 1970 to 1972 Chevelle A Body chassis, enabling a true direct fit without any cutting or welding. By mirroring the original undercarriage geometry, it preserves factory ground clearance and keeps brake and suspension lines in their intended routing paths. Installers use the supplied straps, gaskets, and hardware to secure the tank in minutes, eliminating trial and error and reducing installation time. This level of dimension control also ensures that the tank remains stable beneath the vehicle, preventing unwanted contact with road debris or interference during dynamic driving. The result is a seamless integration that maintains the classic look and functionality of the Chevelle underbody.
Integrated Sealed Pump Module for Vapor Lock Prevention
At the core of this kit lies a sealed pump module that houses the 255 LPH Walbro fuel pump, sending unit, and internal filter within one enclosure. This integrated design keeps fuel pressurized above the intake line at all times, eliminating vapor pockets that cause hesitation or lean spikes under heavy load. The internal vent filter serves as a shield against air intrusion, ensuring continuous flow even under hard acceleration or sustained wide throttle. Precision gaskets and reinforced mounts complete the assembly, delivering leak free operation and consistent pressure in varied driving conditions. With this module in place, vapor lock becomes a concern of the past, preserving engine performance and drivability.
255 LPH Fuel Pump Capacity Supporting 550 HP Setups
Equipped with a 255 liter per hour Walbro pump, this kit is calibrated to support LS and LT engine swaps up to 550 horsepower. The high volume flow prevents fuel starvation during aggressive throttle application and rapid changes in engine demand, maintaining the correct pressure at the rail and injectors. By delivering a steady supply of fuel, the pump safeguards against lean conditions that can harm internal components or trigger trouble codes. Its compatibility with both LS and LT platforms makes it a versatile solution for a spectrum of high output builds. Whether driven on street or track, the system ensures the engine receives precisely the fuel it needs to perform reliably.
Domestic Fabrication for Thermal and Vibration Resistance
All tank components, straps, filler neck, and hardware are manufactured in the United States under stringent quality controls for full material traceability. Domestic fabrication methods emphasize resistance to heat soak common in high output engine bays, preventing accelerated fuel temperature rise that can lead to pressure variance. The robust construction also withstands the vibration and shocks inherent to classic chassis, ensuring the assembly endures repeated thermal cycles and cornering forces without failure. Quick access to replacement parts and upgrades further adds value for restorers and performance enthusiasts who demand long service life and consistent operation. This commitment to local production provides both reliability and support for future maintenance needs.
