1964 Pontiac GTO LS EFI Fuel Tank Kit with 255 LPH Pump
Swapping an LS engine into a 1964 Pontiac GTO requires a fuel system matched to modern injection demands and this fuel tank kit delivers a direct fit design with an integrated Walbro 255 LPH pump to ensure reliable supply up to 550 horsepower. Engineers recessed the pump inside the fuel reservoir to use surrounding gasoline for cooling and minimize cavitation under sustained acceleration. With a calibrated sending unit that ties into factory gauges and OEM style mounting hardware, installation avoids custom adapters while preserving the GTO's authentic underbody lines and accurate level readings during hard cornering.
Immersed 255 LPH Pump Design for Sustained Performance
The Walbro 255 LPH fuel pump sits entirely inside the tank to leverage surrounding gasoline as a natural coolant during operation. By placing the module in a submerged state, the pump avoids heat build up that can degrade performance under continuous acceleration runs. This layout also minimizes cavitation risks when fuel demand spikes in high output LS engines, ensuring uninterrupted delivery up to 550 horsepower. Submerged operation reduces audible noise and vibration compared with external mounting, creating a quieter cabin environment. The exact fit to the 1964 GTO reservoir shape guarantees reliable fuel pickup at varying levels.
Factory Gauge Compatible Sending Unit for Accurate Level Monitoring
The precision calibrated sending unit replicates the stock fuel resistance pattern for seamless integration with original dash gauges. This ensures level readings remain true during hard cornering, sudden braking, or rapid throttle shifts, so drivers can trust their display at all times. Use of the matched connectors and modular harness eliminates the need for adapters or splicing, simplifying the wiring plan and reducing build time. The unit arrives pre calibrated and tested to interface directly with factory circuits, delivering consistent feedback without additional tuning. This alignment preserves the authentic operation of the GTO's instrument cluster.
Comprehensive Kit with OEM Mounting Components for Direct Fit
The kit includes every piece required for installation into the 1964 Pontiac GTO underbody, from tank straps and gaskets to a correctly shaped filler neck and vent filter. All hardware is made to original reference dimensions so bolts and clips align perfectly with factory mounting points, avoiding cutting or fabrication. Pressure tested seals and gaskets leave no room for leaks, while the vent filter guards against fuel contamination from the atmosphere. This cohesive approach reduces install time and complexity, guiding enthusiasts through a straightforward bolt in process. American made components uphold a legacy of quality and durability that modern builds demand.
Engineered for High Output Demands up to 550 Horsepower
Designed to support LS conversions pushing up to 550 horsepower, this fuel tank kit guarantees steady flow rates required by modern electronic injection systems. The high volume output of the in tank pump maintains a consistent fuel rail pressure under peak load, preventing lean spots that can cause detonation in boosted or high compression engines. By matching fuel delivery capacity to engine output, throttle response remains immediate even during extended track sessions or spirited driving. The robust design handles flow surges without starving the engine, giving builders confidence in performance tuning. When combined with classic underbody aesthetics, the kit bridges vintage style with modern power needs.
