1965 Pontiac Lemans A-Body LS EFI Fuel Tank Kit with 255 LPH Pump
Swapping a modern LS powerplant into a 1965 Pontiac Lemans A-Body chassis demands a reliable fuel delivery solution and the 1965 Pontiac Lemans EFI Fuel Tank Kit with 255 LPH Pump delivers an exact fit that preserves original strap mount points and filler neck alignment. This kit features a fully immersed Walbro pump rated at 255 liters per hour to support up to 550 hp without cavitation or vapor lock. An OEM style sending unit matches the stock gauge resistance curve for precise fuel level readings. Manufactured in the USA, it includes pre fitted gaskets, tank straps, vent filter, filler neck, and all installation hardware to simplify installation while maintaining underbody clearance and original chassis rigidity.
Product Overview
The 1965 Pontiac Lemans EFI Fuel Tank Kit with a 255 LPH pump is a comprehensive solution for LS engine integration. This kit transforms the original fuel reservoir into a ready platform for modern electronic injection, supporting output levels up to 550 HP without compromise. The assembly is manufactured in the USA to ensure consistent quality, and it retains all factory mounting points to simplify installation. By using a fuel supply system designed specifically for EFI, the fuel tank kit delivers reliable pressure and volume under every driving condition. A precision fuel sending unit is included to maintain accurate gauge feedback, reducing guesswork during long runs or spirited driving.
Design and Performance
Engineered to optimize flow characteristics, the tank mounted Walbro 255 LPH pump provides a stable stream of fuel needed for high demand situations. This volume capacity caters to elevated horsepower goals while preserving pump life through efficient cooling and immersion. The precision sending unit is calibrated to deliver repeatable level readings, ensuring that drivers remain informed of their remaining range. By preserving factory mount locations, the kit avoids alterations to the chassis floor and keeps the body structure intact. The result is improved throttle response and consistent fuel delivery at all RPM bands, which translates directly into sharper pickup and smoother operation during acceleration or sustained high load.
Integration and Compatibility
This kit integrates seamlessly with LS engine mounting points and the factory cross member to maintain proper alignment of the powerplant. Correct tank and engine placement is essential not only for optimal driveline angles but also to prevent undue strain on hoses and wiring. The combination preserves a low center of gravity, contributing to balanced handling and stable weight distribution. Technicians will appreciate that no cutting or relocation of mounting hardware is required, as all attachment points mirror the OEM layout. The precise fit approach preserves vehicle integrity and enhances the overall reliability of the fuel delivery network.
