1971-1972 Pontiac GTO and Lemans A-Body LS EFI Fuel Tank Kit
When swapping an LS engine into early seventies GTO or Lemans models, the 1971-1972 GTO / Lemans EFI Fuel Tank Kit - 255 LPH Pump - Notched solves tight fuel bay clearance concerns by marrying a precision notched steel shell with a Walbro 255 LPH pump. The lower tank shell contours around tire sidewalls and exhaust passages without requiring any frame rail or brake line modification. Factory mounting points remain intact so the assembly drops into the original fuel bay for a true direct fit that preserves the car's classic profile. Designed to support engines up to 550 hp, it sustains consistent pressure under hard acceleration and highway cruising for reliable LS EFI operation.
Precision Notched Shell Preserves Chassis Clearance
The tank shell is carefully stamped to follow the contours of tire sidewalls and exhaust passages, eliminating any need to alter brake lines or frame rails. This approach maintains original ground clearance while ensuring that full steering lock and suspension travel remain unobstructed. During fabrication, the steel is formed in one continuous piece, so rigidity is retained and stress points are minimized. As a result, the installation fits neatly into the factory fuel bay and preserves the vehicle's classic underbody profile.
In-Tank 255 LPH Walbro Pump for Steady Fuel Delivery
Mounting the high capacity fuel pump inside the tank offers several advantages, including cooler operating temperatures and quieter performance. The Walbro 255 LPH unit is calibrated to deliver constant pressure under hard acceleration and sustained highway speeds, preventing lean-condition risks that could harm engine components. An integrated mesh filter traps debris before it can reach the fuel rail, extending service intervals. This configuration supports up to 550 horsepower, ensuring reliable injection response no matter how demanding the driving conditions become.
Factory Mounting Points Simplify Installation
By retaining the original mounting locations, the kit eliminates the need for custom brackets or trimming, delivering a true direct fit. Installers align the assembly with pre-drilled tabs and secure it using the stock hardware pattern, reducing alignment guesswork and installation time. The filler neck and vent filter attach in the factory openings, so the external tank silhouette remains unchanged. Technicians benefit from a streamlined workflow that preserves the vehicle’s structural integrity and maintains service access behind the rear seat.
Comprehensive Kit with All Swap Essentials
This fuel system package arrives complete with the pump module, sending unit, filler neck, straps, seals and mounting hardware, so no additional parts are required to finish the swap. Each component is tailored to the 1971 and 1972 A-Body Pontiac GTO and Lemans models, ensuring compatibility without modification. Gaskets and vent filters are included to seal the system and manage tank pressure, while heavy duty straps secure the assembly under load. The result is a ready-to-install solution that supports modern LS EFI performance without compromising the car’s original styling.
