1963-1967 Chevy Corvette LS EFI Fuel Tank Kit with 400 LPH Pump
When fitting an LS engine into a Y-Body Corvette, consistent fuel delivery is vital and this fuel tank kit addresses that need with precision. Designed for direct fitment into the Corvette's original tank bay, the assembly features a 400 LPH Walbro pump and a precision sending unit to maintain stable flow under supercharged or high output conditions. Installation is simplified by including all essential mounting hardware and a modular pump module that aligns with factory mounting points.
Efficient Fuel Supply for Supercharged LS Engines
The in-tank pump module houses a 400 LPH Walbro pump calibrated specifically for LS applications, delivering a continuous stream under heavy load. By matching output to the demands of supercharged setups and engines exceeding 550 hp, the system prevents drops in fuel pressure that can cause lean conditions and power loss. This stable flow supports crisp throttle response during hard acceleration or sustained high rpm, while recirculating excess fuel reduces pump heat. The result is maximized horsepower delivery without the risk of fuel starvation in demanding driving scenarios.
Precision Engineered Sending Unit for Accurate Fuel Level Monitoring
A precision engineered sending unit ensures drivers have reliable fuel level data even under hard cornering or vibration. The calibrated float arm and resistance track maintain consistent electrical output, keeping the gauge reading within a safe margin. This level of accuracy prevents unexpected runouts by alerting the operator well before tank depletion, protecting both performance and engine components. In high output builds where fuel reserves vanish quickly, this system safeguards against sudden shutdowns and extends track time.
Direct Fitment for 1963-1967 Corvette Y Body Conversions
Designed to align with the original tank bay of 1963-1967 Corvette Y Body frames, this kit eliminates the need for custom modifications. The pump module drops into the OEM cavity using factory strap locations, and included tank straps, gaskets, and hardware create a leak-proof seal. A purpose-built filler neck and vent filter maintain proper breather operation and safe refueling. By integrating all required components, installation is streamlined, allowing enthusiasts to focus on performance tuning rather than fabrication.
Premium Construction with American Craftsmanship
Manufactured in the USA from premium materials, the fuel tank and internal components are built to endure harsh road and track environments. The tank shell resists corrosion from ethanol-blended fuels, ensuring structural integrity over time and exposure. Robust seals and connectors on the pump module and sending unit reduce service intervals and protect against leaks. This level of quality provides a long lasting solution that enthusiasts can trust, backed by stringent domestic production standards.
