LS EFI Fuel Tank Kit for 1971-1972 Pontiac GTO/Lemans A-Body
When converting a 1971 to 1972 Pontiac GTO or Lemans chassis to EFI clear underbody space is crucial and this notched steel tank kit solves that challenge while providing consistent fuel flow. By contouring the steel shell around tire sidewalls and exhaust pipes installers can use factory mounting points with no trimming or extra brackets needed. Mounted inside the tank the Walbro 255 LPH pump operates at cooler temperatures and sustains pressure under acceleration so engine health is protected during spirited driving or steady highway speeds. Precision fitment ensures that original frame rails and brake lines remain untouched while preserving the classic underbody lines of the A Body.
Contour Matched Shell for Precise Chassis Clearance
The fuel tank's steel shell is stamped in one continuous piece to follow the curves of tire sidewalls and exhaust passages on 1971 to 1972 GTO and Lemans frames. This contour matched design eliminates unwanted interference without altering factory frame rails or brake lines, preserving both structural integrity and ground clearance. By avoiding added brackets or trimming, the tank retains original suspension travel characteristics and handling balance. Careful stamping reduces stress points that could lead to metal fatigue, while the smooth underbody profile maintains the classic silhouette of the A Body chassis beneath modern EFI components.
Walbro 255 LPH Pump Inside Tank for Stable Fuel Delivery
Positioning the Walbro 255 LPH pump inside the tank keeps it submerged in coolant fuel, dramatically lowering operating temperatures and noise compared to external mounts. This arrangement delivers consistent pressure during wide throttle openings and prolonged highway cruising, preventing lean conditions that can harm engine components. An integrated fine mesh inlet filter catches debris before it reaches the fuel rail, extending service intervals and protecting injectors from damage. Rated to support up to 550 horsepower, the internal pump module offers reliable flow under spirited driving or steady high speed runs.
Factory Mount Points Streamline Direct Fit Installation
This kit drops into the original fuel bay using the stock mounting locations, so no custom brackets or body modifications are required. Pre-drilled mounting tabs and an exact match to the OE hardware pattern ensure immediate alignment and secure attachment. The filler neck and vent filter align precisely with existing openings, preserving the exterior under-rear profile and simplifying connection of hard lines and hoses. By maintaining the factory service access behind the rear seat, technicians and enthusiasts alike benefit from straightforward installation and future maintenance access without cutting or rewelding.
Complete Fuel Tank Kit Built for A Body EFI Conversions
Every component needed for a seamless LS engine swap in GTO and Lemans A Body models is included: the 255 LPH Walbro pump module, calibrated sending unit for accurate gauge readings, heavy-duty tank straps, filler neck, vent filter, sealing gaskets, and all necessary mounting hardware. The sending unit is engineered to match factory float characteristics, preventing false fuel level readings after conversion. Ventilation is managed by a purpose-built filter that prevents pressure build up while keeping out contaminants. Together, these parts form a plug-and-play assembly that negates the need to source universal or aftermarket adapters, protecting classic underbody aesthetics and ensuring modern EFI performance.
