1964 Pontiac GTO LS EFI Fuel Tank Kit with 255 LPH Pump
Upgrading a 1964 Pontiac GTO with an LS engine requires a fuel system that matches modern injection demands, and this EFI fuel tank kit equipped with a 255 LPH pump is designed to supply constant flow without extra adapters or bracket work. Engineers placed the pump inside the tank to use surrounding fuel for cooling and to reduce cavitation during sustained acceleration. A calibrated sending unit integrates with factory gauges so level readings remain accurate even under hard cornering. All mounting hardware, straps and fittings match the original underbody layout to let you retain the GTO's authentic look while supporting up to 550 horsepower.
Optimized In Tank Fuel Delivery for Consistent Pressure
Positioning the 255 LPH pump inside the fuel reservoir taps into surrounding gasoline to act as a natural coolant. This approach prevents heat soak during sustained acceleration and maintains stable fuel volume at engine demands up to 550 horsepower. Engineers favored an internal design to minimize cavitation and extend pump life under high load conditions. The immersed layout also reduces rattling and lowers audible hum inside the cabin compared with external pump setups. An exact match to the GTO tank geometry ensures consistent suction as fuel levels change. The continuous flow pattern delivers instant throttle response on track or cruise runs. By harmonizing modern EFI standards with classic underbody lines this kit provides reliable delivery without compromise.
Precision Calibrated Sending Unit for Accurate Level Readings
A precision calibrated sending unit replicates the stock resistance curve to work seamlessly with original dash gauges. Readings remain consistent across heavy cornering, braking or sudden throttle changes so drivers enjoy accurate level data without guessing. Installers avoid aftermarket adapters or custom wiring by using the kit's pre matched connections and hardware. The modular harness included simplifies the wiring run and matches original connector types for plug and play capability. This alignment with factory gauge circuits streamlines the build process and eliminates common fitment issues. The result is true gauge performance and confidence in every mile.
Complete Kit with OEM Style Integration for Simplified Installation
This all inclusive fuel tank kit arrives complete with straps, gaskets, filler neck, vent filter and every piece of mounting hardware needed in one package. Key components mirror original underbody bracketry so the GTO retains its authentic frame layout and visual appeal. Buyers trade cutting or welding for bolt in installation that adapts directly to factory mounts. Every gasket and seal is pressure tested to meet stringent leak prevention standards before leaving the factory. Materials and fittings meet strict OEM tolerances to ensure long term durability. That attention to detail upholds the legacy of the GTO while meeting modern reliability expectations. Enthusiasts at any skill level benefit from accelerated project timelines and robust American craftsmanship.
