1963-1967 Chevy Corvette LS EFI Fuel Tank Kit with 400 LPH Pump
Swapping an LS engine into a 1963 to 1967 Corvette demands dependable fuel delivery and the EFI Fuel Tank Kit with 400 LPH Pump answers with an integrated Walbro unit rated for sustained 400 LPH flow. This internal solution recirculates return fuel to lower pump temperature and resists ethanol blends for reliable operation under boost or extended track sessions. Engineers built the direct fit assembly for the Y body chassis to match factory strap points and include all hardware and gaskets for install without altering the frame while a calibrated sending unit maintains precision fuel level monitoring through cornering and vibration.
Internal Pump Module Delivering Steady 400 LPH Flow
Enclosed within the fuel cell assembly, the 400 liter per hour Walbro pump is positioned to feed the LS engine at elevated throttle and boost settings. By returning surplus fuel back into the tank, the design lowers motor heat and boosts pump longevity during extended track running. This internal placement dampens noise emissions and shields the unit from swings in ambient temperature to hold constant pressure under all conditions. Secured by a precision mounting ring, the pump remains stable through vibration so flow never dips below the rated capacity.
Precision Sending Unit Providing Accurate Fuel Level Data
This sending unit pairs a pivoting float arm with a calibrated resistor track to deliver consistent level feedback on corners and over rough road surfaces. The float geometry absorbs fuel motion so the instrument dash gauge remains steady as the car leans into turns. Its sealed electrical feedthroughs and internal bearings resist corrosion and vapor loss, keeping the signal intact for thousands of miles. Integration uses the stock wiring harness and gauge cluster to avoid extra modules or calibration steps.
Drop In Fitment for Classic Y Body Chassis
Engineered to match the 1963 to 1967 Y shaped chassis of the Corvette, the tank housing uses original strap mounting points and frame dimensions for a drop in install. All gaskets, straps, filler neck, vent filter and hardware come with the kit so no cutting or welding is required on the frame or floor pan. Installation can be completed with basic hand tools and common automotive sockets in a few hours, saving time and preserving the vehicle s factory structure. By keeping the fuel lines and harness alignment true, this solution eliminates guesswork that can lead to leaks or sensor errors.
Fuel Tank Shell Rated for Ethanol Blend Resistance
Crafted in the United States from corrosion proof alloys and ethanol tolerant elastomers, the tank shell withstands modern fuel mixtures without swelling or seal breakdown. Premium connector grommets lock in electrical and fuel line fittings to prevent seepage even under thermal cycling and vibration. All seals and gaskets maintain their rated compression over time to guard against leaks caused by blend additives or moisture. A rigorous inspection process ensures each assembly meets or exceeds the original equipment standard for long term durability.
