1968-1970 Pontiac GTO LS EFI Fuel Tank Kit
Swapping an LS engine into a first generation Pontiac GTO often exposes the factory tank's inability to maintain consistent pressure under sustained demand and this EFI Fuel Tank Kit with 255 LPH pump is engineered to support builds up to 550 hp without fuel starvation. It installs on the A-Body frame using original mounting points so technicians avoid modification work while preserving chassis alignment and suspension clearance. Equipped with a Walbro pump module mounted inside the tank, it draws fuel reliably from multiple angles to prevent vapor formation during cornering and sudden throttle changes. Crafted from heavy gauge steel and supplied with complete fittings, this kit resists corrosion and simplifies plumbing to help maintain steady pressure and smooth throttle response on both street driving and track duty.
Precision Fit to Factory Mount Points
This fuel tank kit is engineered to align exactly with the original frame rails on 1968 to 1970 Pontiac GTO and Lemans models, allowing technicians to preserve chassis geometry and maintain suspension clearance. By matching the factory mounting points, installers avoid cutting, welding, or fabricating adapter brackets, which shortens labor time and reduces the chance of misalignment. Keeping the tank in its intended location also ensures the weight distribution remains as designed by the manufacturer, contributing to predictable handling characteristics under acceleration, cornering, and heavy braking. The direct fit design helps shops deliver consistent, repeatable results on every conversion project while protecting the integrity of the A Body frame.
Integrated Pump Module Ensures Consistent Pressure
At the heart of this kit is a 255 LPH Walbro pump mounted inside the tank, capable of supporting up to 550 horsepower without risk of starvation. Its internal pickup draws fuel from multiple angles, preventing vapor lock when the car is subjected to high g loads or rapid throttle transitions on the street or the track. This reliable supply makes it easier to dial in tuning maps and maintain smooth throttle response under sudden load changes. Locating the pump inside the reservoir also contains noise and heat within the tank, resulting in cooler operation and reduced acoustic intrusion into the cabin.
Robust Steel Construction with Protective Treatment
The replacement tank is built from premium gauge steel to resist corrosion from road debris and moisture, while its rigid shell maintains shape under full load conditions. An internal surface coating prevents sediment accumulation and moisture ingress, which extends service intervals for in line filters and pump maintenance. Engineers sized the steel thickness to withstand common impacts encountered on rough roads without denting or deformation, ensuring uninterrupted fuel flow even in demanding driving environments. This combination of strength and corrosion resistance supports long term reliability for daily use and spirited outings alike.
Comprehensive Kit Reduces Installation Complexity
Every component required for a complete fuel system swap arrives together in one package, including the pump module, sending unit, filler neck, vent filter, straps, gaskets, and all necessary hardware. Key parts are pre assembled with matching connectors and standardized interfaces to eliminate compatibility issues and accelerate both plumbing and wiring tasks. By removing the need for separate part sourcing and test fitting, fabricators can focus on fine tuning rather than troubleshooting fitment concerns. Rigorous quality checks ensure each piece meets original equipment tolerances, delivering a professional level finish on every installation.
