1963-1967 Chevy Corvette LS EFI Fuel Tank Kit with 400 LPH Pump
When fitting an LS engine into a 1963-1967 Corvette Y-Body chassis, maintaining a steady fuel flow under peak power demands is crucial and the 1963-1967 Corvette EFI Fuel Tank Kit with 400 LPH Pump delivers exactly that performance foundation. It uses a 400 LPH Walbro pump housed inside the assembly to sustain pressure during prolonged high rpm operation, while the calibrated sending unit ensures the gauge reads accurately through cornering and vibration. Installation aligns with factory strap locations and includes all mounting hardware for a direct fit into the stock tank bay to avoid fabrication delays. Built from corrosion resistant materials in the USA, this kit is designed to withstand ethanol blends and the stresses of spirited driving on both road and track.
Optimized Fuel Flow for Supercharged LS Engines
The internal fuel pump module houses a 400 LPH Walbro pump that is calibrated to meet the high demand of supercharged and 550 hp LS applications. By providing a constant stream of fuel under sustained high rpm loads, this kit prevents lean conditions that can degrade engine performance or cause detonation. Excess fuel is recirculated to the tank, reducing operating temperature and extending pump life. The result is rock solid fuel pressure that supports crisp throttle response when accelerating hard or maintaining boost.
Precision Level Sensing Under Dynamic Conditions
The precision engineered sending unit features a carefully balanced float arm and high resolution resistance track to deliver accurate gauge readings in all driving scenarios. During hard cornering or aggressive maneuvers, the design compensates for fuel movement in the tank, keeping the electrical signal within tight tolerances. This reliable output alerts the driver well before the tank is depleted, reducing the risk of unexpected shutdown on track or road. Consistent level monitoring is especially important in high output builds where fuel reserves can change rapidly.
Direct Fit Installation for 1963 to 1967 Corvette Y Body Chassis
This kit is engineered to drop straight into the original tank bay of 1963 to 1967 Corvette Y Body frames without any modifications. The pump module aligns with factory strap locations and secures with the supplied straps, gaskets, and hardware for a leak free seal. A purpose built filler neck and vent filter ensure proper breather operation and safe refueling. By including every mounting component, the assembly process is streamlined so you spend less time on fabrication and more time tuning.
Corrosion Resistant American Made Construction
Crafted in the USA from corrosion resistant materials, the fuel tank shell and its internal components are designed to withstand ethanol blends and the stresses of spirited driving. Robust seals and connector interfaces guard against leaks, while the durable enclosure resists chemical attack over years of service. Domestic production standards guarantee consistent quality control and traceability. This level of construction offers enthusiasts a tank solution that holds up under hard use and delivers reliable performance mile after mile.
