1956-1962 Corvette EFI Fuel Tank Kit with 255 LPH Pump
When fitting an LS or LT powerplant into your 1956 to 1962 Corvette this EFI fuel tank kit with a 255 liter per hour pump resolves the challenge of matching modern injection demands while keeping the stock capacity intact. The submersible module drops cleanly into the original tank shell allowing reuse of factory mounting points and filler neck without any custom work. With both pump and sender fully submerged circulation remains quiet and cool even under sustained cornering. A calibrated float assembly and inline vent filter maintain accuracy and guard against contamination for a reliable retrofit.
Form Fit Engineering for 1956 to 1962 Corvette Tanks
This fuel tank kit is precisely shaped to match the original contours of 1956 to 1962 Corvette shells, allowing you to reuse factory mounting points, tank straps, and the filler neck without modification. By mirroring the stock geometry, the module seats cleanly against the factory gaskets, creating a reliable seal that minimizes leak paths and prevents fuel odor intrusion. Installers benefit from a drop-in design that uses existing hardware, cutting assembly time and eliminating weld or cutting work. Maintaining the original underbody clearance and frame rail alignment preserves structural integrity and keeps the vehicle's classic appearance intact throughout the conversion.
400 LPH Walbro Pump Supporting High Output Applications
At 400 liters per hour, the included Walbro pump delivers consistent flow to supercharged and 550+ horsepower engines, preventing lean conditions during rapid throttle changes or sustained high speed. Its advanced internal architecture promotes fast pressure recovery after throttle lift, ensuring injectors remain primed under transient loads. Crafted from robust materials that resist cavitation and wear, the pump stands up to repeated high-demand cycles without performance loss. This level of delivery confidence makes it ideal for both spirited road driving and track use, so you can push your LS or LT powerplant to its limits without risking fuel starvation.
Submerged Module Benefits for Quiet Cool Operation
Integrating both pump and sending unit inside the tank shell offers several operational advantages over external setups. Submersion in fuel provides passive cooling that curbs heat buildup, extending pump life even during hot ambient conditions or long track sessions. Drawing fuel from the lowest point in the shell prevents aeration and maintains stable pressure through hard cornering, braking, or acceleration. The silent running of the in-tank arrangement also enhances cabin comfort by eliminating pump whine, while the enclosed environment shields critical components from road debris and vibration stress.
Integrated Sending Unit and Vent Filtration for Accuracy
The calibrated sending unit delivers precise fuel level feedback, helping to avoid unexpected runouts and maintain driver confidence on long hauls. An inline vent filter protects the module by trapping airborne contaminants before they can enter the pump or injector circuit, preserving fuel quality and reducing wear across the system. Together these elements form a closed-loop safeguard that stabilizes gauge readings and guards against blockages. By combining monitoring and filtration in one module, the kit ensures a clean, reliable supply of fuel and accurate tank information for every drive.
Engineered for precise fit and quiet operation, this kit ensures lasting performance. For the same item but the 255 LPH pump tank kit which offers less horsepower see our 1956-1962 Corvette EFI Fuel Tank kit - 255 LPH Pump.
