1963-1967 Chevy Corvette Y-Body LS EFI Fuel Tank Kit with 255 LPH Pump
When a modern LS engine enters a 1963 to 1967 Corvette Y Body chassis, ensuring the fuel system can keep pace is critical and this EFI Fuel Tank Kit with 255 LPH Pump delivers a tailored solution for up to 550 horsepower. Built from corrosion resistant steel, the new tank slips into the original body brackets and aligns with stock filler and vent openings to preserve classic appearance without chassis modification. The fully submersed Walbro pump draws cool fuel directly and reduces the risk of vapor lock during spirited driving or extended track use. All necessary parts, including pump module, sending unit, straps, wiring and hardware, ship together to follow factory steps and avoid delays at the workbench.
Fully Submerged Walbro Pump Ensures Consistent Fuel Delivery
At the core of this kit, the high-performance 255 LPH Walbro pump remains fully immersed in fuel to draw the coldest possible supply. This submerged arrangement prevents vapor formation even under sustained high load, which helps maintain stable pressure when the engine is pushed to its limits. By keeping the pump below the fuel level, the design also reduces noise and stress on internal components, extending service life. Technicians and enthusiasts benefit from cool fuel delivery that eliminates lean spikes during spirited driving or long track sessions.
Corrosion-Resistant Steel Tank Preserves Chassis Integrity
This replacement tank is formed from heavy gauge, corrosion-resistant steel that matches the contours of '63 through '67 Y-Body Corvette frames. It slips into the original mounting brackets without any chassis modification, preserving the car's structural integrity and classic lines. The filler neck and vent filter align precisely with factory openings, restoring the stock appearance while preventing leaks and corrosion around panel gaps. This approach ensures the installation maintains both authentic style and long-term durability.
Comprehensive Kit Streamlines Installation Workflow
Every component needed for a seamless LS conversion comes included, from the in-tank pump module and sending unit to tank straps, gaskets, filler neck, vent filter and mounting hardware. The parts have been selected to follow GM's factory steps and fasten right first time, which reduces the risk of missing pieces or incorrect fittings. Installers save hours on bench trips by using matched connectors and pre cut wiring lengths. As a result, both professional shops and dedicated DIY builders can complete the fuel system swap with confidence and minimal downtime.
Ample Flow Capacity for 550 HP LS Engine Builds
With a sustained output of 255 liters per hour, this fuel tank kit meets the demands of LS engines making up to 550 horsepower without compromise. The high flow rate ensures rapid recovery during wide throttle openings, preventing fuel starvation under hard acceleration or during aggressive corner exits. Pressure remains consistent across the rpm range, giving tuners room to refine air/fuel ratios for peak efficiency and power. This robust performance headroom supports future engine upgrades without requiring pump replacement.
