LS and LT EFI Fuel Tank Kit with 400 LPH Pump for 1967-1968 Camaro/Firebird
Putting LS and LT power under the hood of a 1967 or 1968 Camaro or Firebird demands a reliable fuel system, and this EFI tank kit delivers with its 400 LPH pump and complete in tank module designed for the stock underbody. It drops in without cutting or welding so the original setup remains intact while the submerged pump prevents vapor lock and cavitation during cornering. A built in sending unit mirrors the internal tank shape to keep gauge readings accurate and a preassembled connector tidies up wiring for a clean installation. Whether tackling a supercharged build or pushing past 550 horsepower these components secure steady flow and crisp throttle response.
Precise Integration with Factory Fuel Tank
The tank module is engineered to drop directly into the original 1967 and 1968 Camaro/Firebird underbody without requiring cutting or welding, preserving the vehicle's structure and corrosion protection. By maintaining the pump submerged, inlet pressure remains constant even when cornering or accelerating aggressively, preventing vapor lock and cavitation. A preassembled connector mates seamlessly with the stock wiring harness to eliminate splices and external lines that can overheat or draw air, resulting in a clean and reliable installation. This precise fit bridges modern EFI demands with classic chassis architecture for a restoration that looks factory-installed yet delivers advanced functionality.
Sustained 400 LPH Pump Output Under Extreme Cornering
At its core, a high-flow 400 LPH Walbro pump provides steady delivery demanded by supercharged and 550+ horsepower LS or LT engines. Its continuous output under high rpm prevents fuel starvation, ensuring stable rail pressure and eliminating lean conditions that can lead to detonation. Testing in hard-turn scenarios shows the submerged design keeps the intake port flooded, so throttle response remains crisp and predictable on track or street. American construction and rigorous quality checks guarantee durability in heat and vibration environments typical of aggressive driving.
Fully Integrated Assembly Simplifies EFI Conversion
This kit unites pump, filter, float arm and sending unit into a single assembly that mirrors the tank's internal shape, providing accurate fuel-level readings across the entire gauge range. Bundled hardware-including tank straps, replacement filler neck, vent filter, gaskets and precision-sized fasteners—ensures all required parts are on hand for a one-step swap. By reducing leak points and wiring complexity, installers can focus on calibration and tuning rather than sourcing components. The result is a streamlined conversion that cuts installation time and minimizes potential service issues down the road.
