1965-1967 Pontiac GTO LS EFI Fuel Tank Kit with 255 LPH Pump
Fuel starvation can derail an LS EFI engine swap in a classic GTO project so this fuel tank kit brings a Walbro 255 LPH pump inside the tank to meet the demands of up to 550 hp. It drops into place on 1965 to 1967 Pontiac A Body chassis using the original mounting points and all hardware is included for a true plug and play fit. Baffling inside the tank keeps fuel in contact with the pump inlet during aggressive cornering while a calibrated sending unit delivers trustworthy gauge readings. Installers will appreciate how this design preserves the factory undercarriage layout and cuts labor time by removing modification needs.
Direct Fit Integration Preserving Factory Undercarriage
The EFI fuel tank kit drops into place on 1965 to 1967 Pontiac GTO A body frames using the original mounting points and hardware. This approach retains the classic undercarriage layout while eliminating the need for body or frame modifications. Installers can rely on precision molded mounting pads that align with factory rails to cut labor time and reduce the chance of alignment errors. Included straps and gaskets ensure a sealed installation from the start and maintain the tank's secure position under dynamic loads.
Anti Slosh Baffle Design Ensuring Consistent Fuel Pickup
Engineered internal baffles keep fuel next to the inlet during sharp turns and rapid stops, preventing momentary starvation that can interrupt engine performance. By maintaining constant contact between fuel and the pump, the system delivers uninterrupted flow even in aggressive driving or track use. This design is critical for an EFI system feeding a high output LS engine that demands steady volume at all times. The baffling also helps reduce air pockets and pressure fluctuations within the tank.
Internal Walbro 255 LPH Pump Placement for Reliable Pressure
Positioning the Walbro 255 LPH pump inside the tank lowers heat soak by submerging the module in cool fuel, which extends service life compared to external pump mounts. A shorter fuel supply path also stabilizes rail pressure under heavy load, supporting up to 550 hp without drop off. The pump connects directly to the factory electrical circuit for a neat installation that avoids messy wire runs. This in tank solution simplifies plumbing and maintains smooth EFI operation under demanding conditions.
Complete Plug and Play Kit Streamlining Installation
This all inclusive kit provides every component needed for a true plug and play swap, including a calibrated fuel level sender, filler neck, vent filter and mounting straps. By matching factory connectors and the stock gauge resistance curve, it delivers accurate readings without adapters or rewiring. Gaskets and hardware are included to ensure fuel tight seals and secure fastening from the moment the tank is in place. The result is a streamlined process that reduces shop hours and preserves original chassis integrity.
