1971-1972 A-Body Pontiac GTO/Lemans LS Swap EFI Fuel Tank Kit
For enthusiasts fitting an LS engine into a 1971 through 1972 Pontiac GTO or Lemans A Body chassis the EFI fuel tank kit ensures consistent fuel flow when demand peaks. The drop in fuel tank uses factory mounting points around the frame rails and includes a 255 LPH pump matched to GTO and Lemans wiring for precise pressure control. Every gasket vent component strap and mounting bracket arrives ready to install so the classic undercarriage remains intact. Crafted in the United States from corrosion resistant materials the assembly sustains steady delivery up to 550 horsepower and integrates a sending module tuned to the original fuel sender circuit.
Precision Engineered for 1971 to 1972 A Body Chassis
The fuel tank molding matches the 1971 to 1972 Pontiac GTO and Lemans frame rails with exceptional accuracy, preserving original clearances around the suspension and brake lines. By using factory mounting points, installers avoid cutting or welding the chassis, which maintains the structural integrity of the underbody. Uniform wall thickness ensures stable fuel pressure under dynamic load and dampens vibration that can lead to noise or fatigue. This precise geometry allows the EFI fuel tank kit to integrate seamlessly, simplifying alignment and reducing installation time while honoring the vehicle's classic layout.
Consistent Fuel Delivery from the 255 LPH Pump
At the heart of the tank assembly is a 255 liter per hour Walbro pump engineered to supply a constant stream of fuel for engines up to 550 horsepower. Its internal current regulation limits voltage spikes and prevents overheating, while the design of the impeller minimizes turbulence for smooth flow under high demand. Maintaining even pressure across all RPM ranges avoids lean spots during wide open throttle, delivering reliable atomization and consistent performance. This results in a responsive throttle feel whether cruising on the highway or pushing the engine on the track.
Comprehensive Kit Contents for Streamlined Installation
This package includes every essential component needed for an EFI swap, from the in-tank pump module and calibrated sending unit to replacement straps, filler neck, vent filter, gaskets, and all mounting hardware. Each part is matched to OEM specifications and rated for modern ethanol blends, so you won't need to source additional adapters or fittings. Pre-terminated connectors and detailed instructions guide technicians through a straightforward direct fit process, reducing the risk of missing pieces and ensuring a smooth transition from the classic sender harness to the new EFI system.
Made in USA Corrosion Resistant Construction
Crafted domestically under rigorous quality controls, the tank assembly utilizes corrosion resistant materials designed to withstand the chemical effects of today's fuel formulations. Every weld and seal undergoes inspection to guarantee leak-free operation and long service life. Manufacturing in the United States allows rapid feedback loops between production and engineering, ensuring consistent dimensional accuracy and swift access to replacement parts or technical support. This focus on local craftsmanship delivers a reliable system built for sustained performance on both street and strip.
