1965-1967 Pontiac GTO A-Body LS EFI Fuel Tank Kit with 255 LPH Pump
Swapping an LS engine into your 1965 to 1967 Pontiac GTO A Body requires a fuel delivery system that can sustain consistent pressure, and this EFI Fuel Tank Kit with a 255 LPH pump integrates a high capacity module into an OEM reservoir that attaches using original chassis mount points. Internal baffling keeps fuel pooled at the inlet during hard cornering or spirited acceleration so the pump remains submerged and free from air pockets that could interrupt EFI operation. Designers also calibrated the sending unit to mirror factory gauge resistance curves, ensuring accurate level readings without extra wiring or adapters. Complete with straps, gaskets, grommets and hardware for a straightforward install, the kit preserves the stock underbody geometry, supports up to 550 horsepower and extends pump service life by immersing it in cool fuel.
Factory Mount Points Ensuring Precise Chassis Alignment
By employing original mounting points on the A Body frame the fuel tank kit installs without cutting welding or altering the undercarriage geometry. Precision molded interface pads keep the assembly aligned with factory rails and crossmembers. This direct fit approach not only preserves structural integrity but also shortens installation time by eliminating guesswork. Included straps and gaskets work in concert with OE style hardware to ensure a secure leak resistant seal under everyday driving or spirited acceleration. Installers benefit from repeatable placement and reduced alignment checks in the shop.
Engineered Baffling for Uninterrupted Fuel Supply
Internal baffles are finely tuned to retain fuel around the inlet area during sharp turns sudden stops and high throttle loads. This design prevents air entrainment and momentary pump starvation that can disrupt electronic fuel injection performance. By maintaining a constant fuel head at the pickup the kit supports steady volume delivery even under aggressive cornering or track use. Consistent supply pressure reduces strain on the pump and maintains stable rail pressure for precise injector response and engine behavior.
Submerged Pump Placement for Thermal Management
Mounting the 255 LPH Walbro pump inside the tank immerses the module in cool fuel which minimizes heat soak and extends service life. This arrangement also shortens the pathway to the fuel rail fostering rapid pressure recovery under demand spikes. The internal pump module ties into the original electrical circuit for a clean installation that avoids extra wiring lanes. Supporting up to 550 horsepower the setup delivers consistent rail pressure for reliable throttle response and engine output.
Comprehensive Kit Contents Simplify Installation
This all in one fuel tank solution ships with every component needed for a straightforward conversion including the pump module sending unit filler neck vent filter straps gaskets and hardware. The calibrated sending unit mirrors factory gauge resistance curves for accurate level readings without adapters or rewiring. By matching existing underbody layout and connectors installers save shop hours and avoid secondary modifications. Every element is crafted to support a seamless LS upgrade in your classic GTO.
