EFI Fuel Tank Kit for LS Swaps in 1963-1967 Chevy Corvette
When modern LS powerplants find their way into a 1963 to 1967 Y-Body Corvette, a reliable fuel supply becomes the top priority and the 1963-1967 Corvette EFI Fuel Tank Kit - 255 LPH Pump handles that task with precision. This EFI Fuel Tank Kit integrates a fully submerged Walbro pump capable of 255 liters per hour, preventing vapor lock and starvation under hard acceleration. Each steel tank slips into original brackets, aligns with factory filler and vent openings, and preserves the classic profile while supporting engine outputs up to 550 horsepower. Included wiring harness, sending unit and installation hardware follow GM routing to reduce bench time and keep your swap project on schedule.
Fully Submerged Pump Design for Stable Fuel Pressure
The heart of this EFI fuel tank kit is a Walbro pump rated at 255 liters per hour, engineered to remain fully immersed in fuel. By drawing the coolest possible liquid, the design virtually eliminates vapor formation that can lead to engine hesitation under sustained load. Submergence also reduces operational noise and lowers mechanical stress on internal parts, resulting in extended service life and fewer maintenance intervals. Enthusiasts benefit from **consistent pressure** during spirited driving or prolonged track sessions, with minimized risk of lean spikes as throttle demand climbs. This approach ensures smooth acceleration and reliable operation when pushing a 550 horsepower LS engine to its limits.
OEM Fitment Guarding Classic Corvette Lines
Constructed from heavy gauge, corrosion resistant steel, the replacement tank conforms precisely to the frame rails of 1963 to 1967 Y Body Corvettes. It slips into the original mounting brackets without altering chassis structure, preserving the car's historic appearance and structural integrity. The filler neck and vent filter align with factory openings to maintain panel gaps and body lines exactly as designed, preventing unsightly leaks and rust around the wheel wells. By avoiding any cutting or welding of the frame, this solution retains the distinct character of the era while delivering modern fuel delivery performance. Long term durability on road or track is ensured thanks to the robust steel construction and careful engineering.
Comprehensive Kit That Streamlines Installation
Every essential component arrives together, including the in-tank pump module, sending unit, tank straps, filler neck, vent filter and mounting hardware. Wiring harnesses and connectors follow GM routing and come pre-cut to match original lengths, eliminating guesswork and bench trials. Installers gain hours of workbench time savings by using factory style fittings and gaskets that fit correctly on first try. This streamlined package suits professional shops and dedicated DIY builders alike, reducing parts shopping and assembly errors. As a result, the entire fuel system swap can be completed with confidence and minimal downtime.
255 LPH Flow Capacity to Support 550 HP Builds
With its sustained 255 liter per hour output, this tank kit meets the fuel demands of LS engines producing up to 550 horsepower without compromise. Rapid flow recovery during wide-open throttle prevents starvation in aggressive corner exits and hard accelerations, ensuring a stable mixture throughout the rpm range. Consistent pressure allows tuners to refine air fuel ratios for optimum power and efficiency, while the ample headroom supports future engine modifications without requiring pump replacement. This generous capacity delivers peace of mind for both street drivers and track competitors seeking dependable fueling under all conditions.
