LS-Compatible Notched EFI Fuel Tank Kit for 1971-1972 Pontiac GTO/Lemans A-Body
For enthusiasts tackling a classic LS swap in a 1971 or 1972 GTO or Lemans chassis, the 1971-1972 GTO / Lemans EFI Fuel Tank Kit - 255 LPH Pump - Notched ensures proper fuel delivery while resolving tight bay clearance. This kit uses a precision notched steel shell contoured around tire sidewalls and exhaust passages so the original frame rails and brake lines remain untouched. By mounting a Walbro 255 LPH pump inside the tank, it provides consistent pressure under acceleration and highway cruising, supporting builds up to 550 hp. Installers benefit from factory mounting points that align with stock hardware, so the assembly drops into the factory fuel bay without extra brackets or trimming.
Precision Notched Shell Preserves Chassis Clearance
The fuel tank shell is expertly formed to follow the curves of tire sidewalls and exhaust passages, eliminating interference without altering frame rails or brake lines. By stamping the steel in a single continuous piece, the design retains structural integrity and minimizes stress points that could lead to fatigue over time. This careful contouring maintains original ground clearance and allows full suspension travel, so you experience no loss of handling precision. The notched profile also preserves the vehicle's classic underbody silhouette, ensuring that the A-Body's authentic look remains intact beneath modern EFI functionality.
In-Tank 255 LPH Pump Delivers Stable Fuel Supply
Positioning the Walbro 255 LPH pump inside the tank provides cooler operating temperatures and quieter performance compared to externally mounted units. This arrangement supports consistent pressure under wide-open throttle bursts and sustained highway speeds, preventing lean spikes that can compromise engine health. An integrated fine mesh filter at the pump inlet protects the fuel rail from debris, extending service intervals and safeguarding injectors. Rated to support builds up to 550 horsepower, the in-tank module ensures reliable flow whether you are carving mountain roads or cruising on the interstate.
Factory Mount Points Simplify Direct Fit Installation
Utilizing original factory mounting points, this kit drops into place with zero need for custom brackets or trimming. Pre-drilled tabs and the stock hardware pattern make alignment straightforward, reducing installation time and eliminating guesswork. The filler neck and vent filter align with the OE openings, so no external modifications are required and the exterior profile remains unchanged. This true direct-fit design streamlines assembly for both professional shops and experienced enthusiasts, preserving the chassis's structural integrity and service access behind the rear seat.
All Inclusive Kit Tailored for A-Body EFI Swaps
This fuel tank package arrives complete with every component needed for a seamless LS conversion in 1971–1972 Pontiac GTO and Lemans models. The sending unit, tank straps, filler neck, vent filter, gaskets and all mounting hardware are specifically engineered for the A-Body chassis. Each part is precision matched to the factory fuel bay, so there is no need to source additional items or adapt universal components. The result is a plug-and-play solution that preserves classic styling while supporting modern EFI performance demands.
