LS Swap Fuel Tank Kit with 255 LPH Pump for 1971-1972 Pontiac GTO/Lemans A-Body
When installing an LS powertrain into a 1971 and 1972 GTO or Lemans chassis, consistent fuel delivery is non negotiable and this EFI fuel tank kit with an integrated 255 LPH pump ensures steady flow under load. Featuring a precision fit around the A Body frame rails, the tank uses factory mounting points to remove the need for cutting or welding and maintain original clearances. Installation includes straps, gaskets and vent hardware for a direct, drop in swap that preserves the classic undercarriage layout. At its core the 255 LPH pump sustains constant pressure for engines up to 550 horsepower and integrates a sending module specifically tuned to the GTO and Lemans fuel sender wiring.
Precision Fit Design for 1971 to 1972 A Body Chassis
The EFI fuel tank kit is molded to the exact shape of the 1971 to 1972 Pontiac GTO and Lemans frame rails, preserving the original footprint and mounting points. This precise geometry allows the tank to nestle into the A Body structure without cutting or welding, maintaining clearance around suspension and brake lines. Uniform wall thickness supports consistent fuel pressure while reducing vibration and chatter. By aligning with stock dimensions and using factory hardware, installers can achieve a secure fit that upholds the classic undercarriage layout and simplifies the LS powertrain integration.
Integrated 255 LPH Pump Performance Benefits
At the heart of the assembly is a 255 liter per hour Walbro unit engineered to deliver a steady stream of fuel for engines up to 550 horsepower. Consistent flow under wide open throttle prevents lean conditions and ensures smooth atomization across the range of engine speeds. The pump's internal current regulation and thermal management design help reduce heat soak and extend service life. Whether cruising or under heavy load, drivers can count on even fuel pressure and responsive throttle feel.
Comprehensive Kit Components Streamline Installation
This all inclusive package brings together every required part for an EFI swap in one shipment. Included are the in tank module, sending unit calibrated for factory sender wiring, replacement straps, filler neck, vent filter, gaskets and mounting hardware. Each part matches or surpasses OEM standards for compatibility with modern ethanol blends. With detailed instructions and pre fitted connectors, technicians can minimize downtime and avoid sourcing missing pieces during critical installation stages.
Domestic Production Ensures Consistent Quality
Manufactured in the United States under rigorous quality controls, this EFI tank kit benefits from thorough inspections at each assembly step. Material selection and fabrication processes are optimized to resist corrosion and chemical attack from today's fuels. Domestic production also allows detailed oversight of every batch and faster access to replacement parts or technical support. This local focus on precision and craftsmanship results in a reliable system designed for sustained performance on both road and track.
