Direct-Fit OEM Replacement Fuel Tank Assembly
Swapping a 6.6L L8T LT engine into a classic chassis often turns on reliable fueling and the Direct-Fit OEM Replacement Fuel Tank Assembly steps in to satisfy that core requirement. It mounts to stock frame points and houses a 400 LPH in tank pump module that minimizes vapor lock and maintains consistent fuel pressure during heavy acceleration. A matched sending unit delivers precise level readings when cornering or braking and steel construction stands up to corrosion and vibration for long term service. This fully inclusive assembly eliminates fitting headaches by providing factory geometry alignment and all required hardware for a straightforward installation on vintage Chevy EFI conversions.
In Tank Fuel Pump Module Delivers Consistent Pressure
This fuel tank assembly incorporates a high-capacity 400 LPH Walbro pump module fully contained within the tank to reduce vapor lock and eliminate pressure variation during throttle transitions. By situating the pump below the fuel surface, heat soak is minimized and fuel remains cool even under extended high demand. The integrated strainer prevents debris from entering the pump while the internal check valve holds rail pressure during rapid throttle lifts. This layout removes the need for external return lines and reduces plumbing complexity, improving overall reliability. Installers benefit from a unified design that maintains steady pressure regardless of cornering forces or sustained acceleration.
400 LPH Walbro Pump Supports Supercharged and 550+ HP Engines
The 400 LPH Walbro pump is engineered to meet the flow requirements of builds exceeding 550 horsepower, making it well suited for boosted and high output applications. Its placement in the fuel reservoir ensures that the pump sees a constant supply of cool fuel, which reduces the risk of vapor formation and maintains flow consistency at high rpm. This capacity margin prevents lean spikes during wide open throttle or sudden load increases, helping to protect engine internals from damage. Whether you are running a supercharged setup or preparing for track duty, this pump provides the headroom needed for reliable fuel delivery without compromise.
Precision Shaping Sending Unit for Accurate Level Readings
The sending unit is custom shaped to match the original tank contour, ensuring precise gauge readings under dynamic driving conditions. Modern electronic fuel injection relies on accurate level data for pump control and diagnostic feedback, making reliable sensing vital to both performance and safety. Calibration remains consistent throughout the full range of fuel travel, so drivers avoid unexpected dry runs during spirited cornering or steep braking. This level of accuracy enhances confidence in gauge readings, allowing you to focus on driving without second guessing remaining fuel volume.
Comprehensive Direct Fit Kit Streamlines Vintage Chevy EFI Installation
This complete assembly arrives with all components required for a direct fit on 1949 to 1952 Chevrolet EFI conversions, including tank straps, filler neck, vent filter, gaskets and mounting hardware. Factory frame mount compatibility eliminates the need for custom brackets or modifications, significantly reducing installation time and potential leak points. Welded steel construction resists corrosion and stands up to chassis vibration, so the assembly delivers service life that parallels the original design. By providing every part preselected for precise fitment, this kit ensures a professional installation outcome and frees you from the hassle of sourcing individual adapters or fittings.
