EFI LS and LT Fuel Tank Kit for 1970-1973 Camaro/Firebird F-Body
When tackling an LS or LT engine swap into a first generation Camaro or Firebird F body, maintaining consistent fuel flow becomes crucial under heavy loads. This EFI fuel tank kit with a 400 LPH pump is engineered to deliver reliable output under sustained demand in high horsepower applications pushing beyond 550 hp. Integrated vent filters trap airborne debris before it can contaminate the system, and precision O ring seals lock in vapors and prevent leaks. Installation stays true to factory frame rail mounting points with purpose built straps and hardware, reducing install time while preserving original underbody lines.
Precision Fuel Delivery from 400 LPH Walbro Pump
The heart of this kit is a 400 LPH Walbro pump engineered to sustain engines above 550 horsepower without hesitation. Its precision-balanced rotors and hardened steel internals deliver consistent pressure across the RPM range, eliminating fuel starvation during rapid throttle transitions or extended high load. Maintaining stable rail pressure helps injectors deliver the exact volume needed for optimal combustion timing, improving throttle response and engine smoothness. The design also leaves capacity for future power upgrades without swapping to a higher capacity unit, ensuring your fuel system remains adaptable.
Integrated Filtration and O ring Seal Protection
Protecting fuel quality begins with premium vent filters that capture airborne dust and moisture before they reach the pump module. At every junction, purpose-molded O ring seals lock out contaminants and seal in vapors, preventing leaks and corrosion over time. This two-stage defense keeps fuel clean, reducing abrasive wear on pump components and limiting the risk of injector fouling. As a result, maintenance intervals are extended and overall system reliability improves, so you can focus on the drive rather than frequent service checks.
Tailored Design for LS or LT Engine Installations
This fuel tank kit has been developed specifically for LS and LT engine swaps, matching factory fuel delivery characteristics while accommodating higher output demands. The sending unit and pump module are oriented to provide accurate fuel level readings without modification to the stock gauge cluster, preserving driver feedback. By ensuring precise fuel supply under all operating conditions, injectors can operate at peak efficiency and deliver consistent atomization across varying loads. The result is seamless integration with Chevrolet Gen III and Gen V platforms and a marked improvement in throttle consistency.
Streamlined Underbody Fit on 1970 to 1973 Camaro and Firebird
Installation follows the factory frame rail layout on first generation F body chassis, using purpose-built tank straps and mounting hardware to drop directly into place. There is no need for cutting, welding or custom brackets, which speeds up the swap process and protects the original underbody profile. The filler neck, gaskets and sending unit arrive preassembled in the tank, allowing a one-stage installation once the stock tank is removed. Clear instructions guide technicians through each step, resulting in a secure, vibration-resistant fit that preserves the classic appearance beneath the car.
