1968-1974 Chevy Corvette LS EFI Fuel Tank Kit with 255 LPH Pump
When planning an LS engine swap into your 1968-1974 Corvette, reliable fuel delivery begins with the correct tank setup. This EFI conversion kit fits the Y-Body chassis exactly and removes the need for guesswork or modifications to factory mounting points. It features a high-performance 255 LPH Walbro pump that supports engines up to 550 horsepower with consistent flow under varying demands. Clear installation instructions guide you through the swap, making it accessible for both seasoned mechanics and those tackling their first Corvette project.
Precision Fit for 1968 to 1974 Corvette Y Body Chassis
This fuel tank kit is engineered to match the original Y Body mounting points and clearances of your Corvette, eliminating any need for cutting or reshaping the chassis. CNC-validated dimensions ensure the tank sits securely in the factory cradle, maintaining proper alignment with the fuel filler and venting system. By preserving the stock geometry, this design reduces stress on tank straps and prevents fuel line kinking under hard cornering. The result is a reliable installation that retains the subtle lines and underbody integrity of your classic Corvette.
Walbro 255 LPH Pump Supporting Engines up to 550 Horsepower
The integrated Walbro pump delivers a steady 255 liters per hour of flow, engineered to satisfy fuel demands for engines producing up to 550 hp. Its internal diaphragm design maintains consistent pressure even at high RPMs or under sustained wide-open throttle conditions. This low-noise, in-tank unit also promotes cooler fuel temperatures by drawing from the bottom of the reservoir, reducing the risk of vapor lock in hot driving scenarios. Whether cruising on the highway or pushing the limits on track day, you can rely on uninterrupted fuel delivery.
Complete Fuel System Kit for Seamless Integration
This all-in-one package includes the in-tank pump module, sending unit, filler neck, vent filter, premium gaskets, tank straps and installation hardware. Each component is matched to the fuel tank and calibrated to work together in the stock fuel return and venting network. The sending unit provides accurate gauge readings, while the filler neck and vent filter ensure proper vapor management. By offering every part in one box, you avoid compatibility issues and additional trips to the parts store, saving both time and frustration.
Streamlined Installation with Clear Guidance
Comprehensive instructions guide you through removal of the old tank and installation of the new EFI conversion kit in logical stages. Detailed diagrams show routing for fuel lines and wiring harness connections, and torque specifications are provided for all fasteners. Whether you are a seasoned mechanic or tackling your first major project, this approach reduces the chance of errors and helps you complete the job in a single weekend. Proper sealing and secure strap tension are emphasized to ensure safe, leak-free operation every time you fire up the engine.
