1971-1972 Pontiac GTO/Lemans A-Body LS and LT EFI Fuel Tank Kit
For LS and LT engine swaps in 1971 to 1972 A-Body Pontiac GTO and Lemans models, the 1971 to 1972 GTO / Lemans EFI Fuel Tank Kit 400 LPH Pump provides the robust fuel supply required for supercharged or 550 horsepower plus applications. The 400 LPH pump from Walbro is housed in a complete in tank module and rated for over 550 horsepower, while the included sending unit, tank straps, filler neck and vent filter simplify adaptation to factory mounting points. All gaskets and installation hardware are supplied to enable direct fit integration, preserve original fuel line routing and maintain consistent flow under aggressive acceleration and high load conditions.
Precise Fitment for 1971-1972 GTO and Lemans
The 1971-1972 GTO / Lemans EFI Fuel Tank Kit is engineered to slot directly into the factory location without trimming or filler panels. Every dimension mirrors the original tank geometry to preserve chassis integrity and maintain suspension clearance. By matching the stock mounting towers and vent passage, it retains the factory fuel lines and filler neck orientation. This exact fitment reduces installation time and ensures the restored appearance remains authentic. Technicians and restorers benefit from a solution that requires no additional brackets or custom shaping.
Robust Fuel Delivery System Featuring a High-capacity Pump
At its core is a high-capacity 400 LPH Walbro pump rated to support engines producing more than 550 horsepower. This unit provides a reserve of flow that prevents pressure drop during cornering, hard acceleration and prolonged highway runs. Its efficient motor design draws minimal electrical current while maintaining a steady output up to the raw edge of its capacity. The result is stable fuel pressure under extreme duty cycles, reducing the chance of lean conditions that can damage high-performance engines. In addition, the internal baffle design minimizes fuel slosh and air ingestion, delivering smooth operation even when fuel level approaches low reserve.
Seamless Integration with LS and LT Engine Swaps via MuscleRods
This tank kit supports both LS and LT engine configurations and is fully compatible with MuscleRods mount systems. By aligning the tank pickup and return ports with the swap-specific routing, it ensures proper engine placement and maintains optimal drivetrain angles. This partnership guarantees that fuel lines clear crossmembers and frame rails without interference, so the fuel delivery loop remains unobstructed. Whether it's a street cruiser or a track car, this integration preserves the geometry engineered by MuscleRods and contributes to consistent throttle response and long-term reliability.
