1963-1967 Chevy Corvette LS EFI Fuel Tank Kit with 255 LPH Pump
Swapping an LS engine into a classic '63 through '67 Corvette demands a reliable fuel supply so this complete tank kit integrates a 255 LPH Walbro pump with a corrosion resistant steel reservoir. It preserves the Y Body frame mounts and original clearance while ensuring consistent flow at wide throttle openings. Installation proceeds without chassis modification thanks to factory mounting geometry. By maintaining cool fuel temperatures in the reservoir module, vapor lock is minimized even under sustained load during spirited driving or track sessions. Each component follows original underbody contours, preserving the Corvette profile while providing modern fuel delivery reliability.
Consistent Fuel Flow and Vapor Lock Reduction
At the core of this fuel tank kit is the 255 liter per hour Walbro pump designed for smooth delivery at every throttle position. Integrated within the tank housing, the pump stays submerged so it draws cool fluid directly and resists vapor formation under demanding use. This arrangement reduces the chance of air pockets that can cause the engine to run lean under heavy load or during hot weather. By maintaining stable pressure, the kit ensures rapid throttle response on straights or winding back roads. Engines equipped with this system benefit from fewer interruptions in supply and a more predictable torque curve during spirited driving.
Factory Fitment and Corrosion Resistant Reservoir
Engineers crafted the replacement tank from corrosion resistant steel to match original GM contours so it slips into place using the existing mounting brackets on the Y body frame of Corvette models from 1963 through 1967. No fabrication or chassis modification is needed, which keeps installation time to a minimum and protects the vehicle's structural integrity. The module design replicates the original tank shape and mounting points exactly, maintaining the profile that defines classic Corvette appeal. Even the filler neck and vent filter locations align precisely with the bodywork, preserving the traditional experience at the pump. This attention to factory style fitment and sturdy material choice means owners avoid unsightly gaps, rust concerns or the need for custom trim.
Comprehensive Module Kit Streamlines Installation
This system bundles the in tank pump module and sending unit with tank straps, filler neck, vent filter, gaskets and all required hardware. Each component ships in sequence to follow the assembly steps, which reduces errors and limits trips back to the parts bin. Since the design uses standard fuel lines and original mounting points, professional shops and skilled enthusiasts alike can complete the swap without custom fabrication. By including every fitting and seal, the kit ensures a leak free installation that meets or exceeds restoration standards. The result is a modernized fuel solution that installs as easily as the stock unit did decades ago.
Support for LS Engines Producing up to 550 Horsepower
With a flow rate sufficient for power outputs as high as 550 horsepower, this tank and pump combination meets the demands of serious LS builds. Whether the engine runs on pump gas or a higher octane race blend, the pump sustains adequate volume during sustained high rpm without strain. This capacity makes it ideal for both street driven Corvettes and track day machines that require repeatable performance over long sessions. The robust internals resist wear over time, so even if power levels increase, the system remains a reliable foundation. Owners gain confidence knowing their fuel delivery can handle future upgrades without compromise.
