1967-1968 Camaro/Firebird LS and LT EFI Fuel Tank Kit with 400 LPH Pump
For anyone swapping an LS or LT engine into a 1967 or 1968 Camaro or Firebird, this EFI fuel tank kit with its 400 LPH pump is designed to sustain a constant flow under heavy throttle loads. Its in tank module installs under the original fuel tank without cutting or welding so chassis integrity and corrosion protection stay intact. By keeping the pump fully submerged, the assembly prevents vapor lock and cavitation during hard cornering, maintaining rail pressure under supercharged or 550 plus horsepower demands. A built in sending unit matches the tank interior for precise gauge readings while the preassembled connector cleans up wiring for a neat installation.
Seamless In Tank Module Preserves Chassis Integrity
The in tank module installs beneath the original fuel reservoir without cutting or welding the chassis, preserving structural rigidity and factory corrosion protection for the underbody. By keeping the pump fully submerged, inlet pressure remains constant even during tight turns or abrupt acceleration, eliminating vapor lock and fuel cavitation that can starve modern engines. The preassembled connector integrates with the stock wiring harness to remove splices and external lines that may draw in air or overheat under hood. This design merges advanced EFI requirements with classic sheetmetal integrity, making the swap appear as if it came from the factory.
400 LPH Walbro Pump Ensures Consistent Flow at High Demand
Equipped with a 400 LPH Walbro pump, this kit delivers the continuous flow necessary to support supercharged powerplants and engines producing over 550 horsepower. Its submerged mounting maintains a flooded intake, sustaining rail pressure under sustained high rpm and severe cornering loads to prevent lean conditions and detonation. Sharp throttle response is guaranteed through consistent fuel delivery, which proves critical when pushing boosted or naturally aspirated engines to their limits. Manufactured in the USA under tight quality controls, the pump resists heat soak and vibration common in aggressive driving environments.
Integrated Sending Unit and Kit Hardware Simplify Setup
A sending unit shaped to match the tank interior provides precise fuel level readings at all times, avoiding phantom empty or full indications that can hamper long drives or track sessions. Bundled hardware-including tank straps, replacement filler neck, vent filter, gaskets and precision fasteners-ensures installers have every part needed for a one step swap without sourcing extra components. The integrated pump, filter and sensor assembly reduces potential leak points and electrical failures, letting technicians focus on calibration and tuning rather than troubleshooting. Together, these elements streamline the conversion and deliver reliable operation from startup to redline.
