EFI Fuel Tank Kit with 255 LPH Pump for 1965-1967 A-Body GTO LS Swap
When converting a 1965 through 1967 GTO to LS EFI, fuel delivery reliability is crucial, and the 1965-1967 Pontiac GTO EFI Fuel Tank Kit - 255 LPH Pump answers this need by housing a robust Walbro module inside the tank. It installs using factory mounting points on the A Body chassis with no modifications required and includes internal baffling that maintains fuel at the pump inlet during hard cornering. A calibrated sending unit ensures accurate gauge readings, and the complete kit ships with all straps, gaskets and hardware for a straightforward install that preserves the undercarriage layout.
Precision Fit for Classic A Body Chassis
This fuel tank kit installs directly on 1965 to 1967 Pontiac A Body frames using original mounting points and included hardware. Precision molded pads ensure perfect alignment with factory rails, preserving the undercarriage layout without any frame work or welding. By retaining the stock mounting geometry, the kit reduces labor time and minimizes the risk of misalignment. Supplied straps and gaskets deliver a secure, leak free seal under all driving conditions.
Anti Slosh Baffles for Steady Fuel Supply
Internal baffling is engineered to keep fuel against the inlet during sharp turns, hard stops, and spirited acceleration. This design prevents momentary starvation that can interrupt EFI function when cornering or braking. By maintaining constant contact between fuel and pump, air pockets and pressure fluctuations are reduced, ensuring uninterrupted flow. For a high output LS swap that demands steady volume, these baffles are essential to reliable performance.
Submerged Walbro Pump for Stable Rail Pressure
Positioning the Walbro 255 LPH pump inside the tank immerses the module in cool fuel, which lowers heat soak and extends service life. A shorter fuel path from tank to rail further stabilizes pressure under demanding conditions, supporting up to 550 horsepower without drop off. The pump ties into the factory electrical circuit for a neat, hidden installation. This in-tank setup simplifies plumbing and sustains smooth EFI operation through long drives.
Complete Install Kit for Time Saving Assembly
This all-inclusive kit ships with every component needed for a straightforward swap: in-tank module, sending unit, filler neck, vent filter, straps, gaskets, and hardware. The calibrated sending unit follows the stock gauge resistance curve for accurate level readings without extra adapters or rewiring. By preserving the original underbody layout and matching factory connectors, installers save shop hours and avoid secondary modifications.
