1963-1967 Chevy Corvette LS EFI Fuel Tank Kit 400 LPH Pump
When fitting an LS engine into a 1963-1967 Corvette, consistent fuel delivery can make or break performance and this EFI tank kit offers the solution. Inside its corrosion resistant steel shell, the 400 LPH Walbro pump maintains steady pressure even under continuous high load. A precision sending unit delivers accurate fuel level readings while the complete hardware kit ensures swift installation without altering the Y-Body floor. Each component is made in the USA for long-lasting performance in demanding driving conditions.
Optimized Fuel Delivery for Supercharged LS Engines
The tank mounted pump module features a 400 LPH Walbro unit engineered to support engines beyond 550 horsepower. By delivering a consistent volume of fuel under sustained heavy load, it prevents pressure drop during rapid acceleration or extended high speed runs. This steady flow ensures the engine's injectors operate within their ideal range, preserving throttle response and combustion efficiency even in the most demanding driving scenarios.
Precision Fuel Level Monitoring for Runout Prevention
The precision engineered sending unit continuously measures fuel level within tight tolerances, translating into accurate gauge readings on the dash. With improved measurement repeatability, drivers can rely on real-time data to judge remaining range, reducing the risk of unexpected runouts. Accurate level feedback also aids in tuning fuel maps for optimal power delivery throughout the tank's capacity.
Complete Hardware Kit for Seamless LS Swap Integration
Specifically designed for 1963-1967 Corvette conversions, this kit includes the pump module, sending unit, tank straps, filler neck, vent filter, gaskets, and all necessary mounting hardware. Each piece is crafted to match the original tank footprint, allowing installation without modifying the factory floor pans. This integration cuts installation time and minimizes alignment issues, making it ideal for both professional installers and DIY enthusiasts.
Premium Materials and American Craftsmanship
Every component resides inside a corrosion resistant steel shell and is manufactured in the USA, reflecting strict quality control standards. The use of robust materials ensures resistance to ethanol blends and road salt, while precision fabrication methods maintain structural integrity under vibration and thermal cycling. As a result, this fuel tank kit delivers reliable service life in harsh environments, mile after mile.
