1971-1972 GTO/Lemans A-Body LS EFI Fuel Tank Kit with 255LPH Pump
Swapping an LS powerplant into a 1971 to 1972 Pontiac GTO or Lemans A-Body often stalls without a dependable supply of fuel, and this EFI tank kit ensures consistent delivery via a 255 liter per hour pump rated to feed up to 550 horsepower. The preformed corrosion resistant tank bolts to factory frame mounts to preserve original underbody clearance and resist modern ethanol blends. Plus, each seal, vent hose, bracket and gasket arrives preassembled with preterminated connectors and factory grade hardware to eliminate guesswork in a chassis specific fit. Built in the United States under strict quality controls, the assembly provides accurate level readings and unwavering pressure under load.
Precision Fit for Classic GTO and Lemans A Body Chassis
The preformed tank is molded to match the frame rails of 1971 to 1972 Pontiac GTO and Lemans A Body vehicles with exceptional accuracy, preserving original underbody clearance. By using factory mounting points installers avoid cutting or welding into the frame, which maintains structural integrity. Consistent wall thickness reduces vibration under load and keeps pressure steady when the pump is delivering fuel during high demand. This precise geometry streamlines alignment and installation, protecting brake lines and suspension components by respecting the classic layout without modifications.
Consistent Delivery from the 255 LPH Walbro Fuel Pump
At the heart of this assembly is a 255 liter per hour Walbro pump calibrated to support engines up to 550 horsepower with unwavering flow. Internal current regulation limits voltage spikes and prevents reverse flow, safeguarding the pump under heavy acceleration. The specialized impeller design minimizes turbulence to maintain a smooth fuel stream even at wide open throttle, preventing lean conditions when power demand spikes. By sustaining stable pressure across the RPM band, the system ensures accurate atomization for crisp throttle response whether on the street or the track.
Complete EFI Integration with Preassembled Components
This all inclusive kit arrives ready to install with every necessary part: in tank pump module, calibrated sending unit, tank straps, filler neck, vent filter, gaskets and factory grade hardware. Each piece is manufactured to precise specifications and rated for modern ethanol blends, eliminating compatibility issues. Preterminated connectors guide wiring in a straightforward sequence, while detailed instructions tie the new module into the original sender circuit so fuel level readings remain accurate. The result is a streamlined swap that keeps classic underbody clearance intact and removes post-purchase surprises.
American Made Corrosion Resistant Tank Construction
Produced in the United States under rigorous quality controls, the fuel tank uses corrosion resistant alloys formulated to resist ethanol and contemporary fuel additives. Every weld and seal undergoes thorough inspection to guarantee leak free performance under prolonged operation and road exposure. Domestic manufacturing allows rapid collaboration between engineering and assembly, ensuring tight dimensional tolerances and prompt support for replacement parts. The high grade materials and finishes deliver durable service life and reliable resistance to harsh fuel chemistries and stress cycles.
