1971-1972 Pontiac GTO/Lemans A-Body LS EFI Notched Fuel Tank Kit
When installing an LS engine in a 1971 and 1972 Pontiac GTO or Lemans A Body chassis the 1971 1972 GTO Lemans EFI Fuel Tank Kit with 255 LPH pump notched design solves underbody clearance and fuel delivery challenges that stock units cannot handle. This precision stamped steel tank wraps around tire wells and exhaust runs while preserving original frame rail mounting points. It comes complete with a fuel pump module featuring a 255 LPH Walbro pump and calibrated sending unit to support fuel flow for engines up to 550 hp. All necessary hardware including tank straps gaskets a filler neck vent filter and installation fittings is supplied for a direct fit that aligns with factory holes and existing body openings while maintaining reliable performance on highway or track.
Design and Fitment
The 1971-1972 GTO Lemans EFI fuel tank kit features a precision notched design to clear narrow tire schedules and curved exhaust runs. This notched section matches the original fuel tank envelope to fit inside the rear frame rails without modification. The shape is verified to clear both factory and aftermarket wheels with wider section widths, making it ideal for custom setups without cutting the floor pan. By maintaining the stock profile and mounting points, the kit preserves the classic look of your GTO or Lemans while ensuring proper underbody geometry and safe fuel line routing.
Fuel Delivery Performance
At its core is a 255 liter per hour Walbro fuel pump that delivers consistent flow under varying demand. This pump capacity supports up to 550 horsepower when paired with compatible injectors and regulators. Its internal strainer helps protect the high pressure system from debris while the electrical terminal design minimizes voltage drop. The result is steady pressure at wide open throttle and minimal risk of vapor lock under sustained load. Drivers will notice improved throttle tip in all rpm ranges.
Engine Integration
This kit is engineered for seamless LS engine installation in A body GTO and Lemans chassis. It works with commonly available LS engine mounts to ensure correct engine placement and proper driveline angle. Pickup location in the tank is optimized to reduce turbulence and maintain coverage at cornering loads. Fuel inlet and return fittings align with original mounting tabs so lines follow a direct path along the frame rail. Installation time is reduced and there is no need for additional adapters or cross members.
Craftsmanship and Durability
Manufactured by BRP Hot Rods, the assembly reflects a focus on robust build quality. The steel shell is precision stamped for uniform wall thickness and coated inside and out for corrosion resistance. Welded brackets and integrated mounting points align precisely to factory dimensions and are inspected for weld integrity. Ground and smoothed seams prevent rattles and ease service access. This precision construction ensures long service life and professional fit that complements the restoration of your muscle car.
