1968-1970 Pontiac GTO/Lemans LS EFI Fuel Tank Kit
When tackling an LS engine swap in a 1968-1970 Pontiac GTO or Lemans, ensuring steady fuel delivery and proper chassis clearance is a common hurdle. This EFI fuel tank kit features a notched shape that clears room for exhaust routing and tire movement while the 255 LPH pump sustains consistent flow. Every component from the integrated sending unit to the leak-proof gaskets aligns precisely with the A-Body chassis for a straightforward fit. Support for builds up to 550 horsepower removes concerns about fuel starvation under heavy load.
Notched Tank Shape for Exhaust and Tire Clearance
The uniquely cut tank profile is engineered to provide generous room around the exhaust path and rear wheel travel. By incorporating a recessed area into the fuel tank body, this design prevents interference with header pipes and heavy cornering loads, safeguarding both fuel system integrity and suspension movement. Classic GTO and Lemans frames often pose tight clearances; this solution eliminates guesswork and trimming, allowing builders to maintain stock routing while upgrading to EFI. The precise contours of the notch ensure that heat and vibration from the exhaust remain isolated from the tank shell, reducing long-term stress on welds and material.
Consistent Fuel Flow from 255 LPH Walbro Pump
At the heart of this kit lies a 255 liter per hour Walbro pump capable of supporting builds up to 550 horsepower without fuel starvation. Mounted within the tank, it draws fuel gently to prevent aeration and cavitation under heavy acceleration or sustained high-load conditions. This high-capacity unit maintains stable pressure across the full RPM band, so throttle response remains sharp even during spirited driving. Combined with a calibrated sending unit and precision gaskets, the assembly guarantees leak-free operation and accurate level readings, promoting confidence on both the street and track.
Straightforward A Body Fitment Simplifies Installation
Designed specifically for 1968 to 1970 Pontiac GTO and Lemans A body chassis, every component in this kit aligns with factory mounting points and fuel lines. Builders benefit from a direct-fit filler neck that mates with the original sheet metal opening and tank straps that hold the unit securely without modifications. The inclusion of vent filters and hardware eliminates the need for aftermarket adapters, while the integrated sending unit means no extra electrical splices or custom brackets. Whether you're a first-time swapper or a seasoned technician, this installation process minimizes downtime and keeps the project on schedule.
