1970-1973 Camaro/Firebird EFI Fuel Tank Kit with 255 LPH Pump for LS Swaps
If you are installing a Chevrolet LS powerplant into a first generation Camaro or Firebird, the 1970 to 1973 Camaro / Firebird EFI Fuel Tank Kit - 255 LPH Pump provides an integrated solution that preserves original chassis geometry and delivers reliable fuel pressure. Engineered for LS swaps, this kit features an in tank module with a high capacity 255 LPH pump, a matched sending unit, and stainless steel tank straps. Precision molded O ring seals and supplied gaskets create a leak resistant barrier, while the included filler neck and vent filter guide fuel smoothly to the module. Rated to support up to 550 hp, the assembly installs through the factory opening on F bodies without any cutting or trimming. Complete installation hardware simplifies mounting and hose routing, giving builders a direct fit path to consistent fuel delivery under hard cornering and launch conditions.
Engine Integration and Alignment
The 1970-1973 Camaro and Firebird EFI Fuel Tank Kit has been engineered to work in concert with MuscleRods mounts, guaranteeing precise LS engine placement and optimized drivetrain angles. By matching the factory mounting points on F-body frames, this design maintains correct pinion angle to the rear axle, reduces vibration and minimizes driveline stress. Installation aligns the pump inlet directly with the engine feed line, promoting consistent pressure under dynamic driving conditions.
Fuel Delivery Performance
At the heart of this kit, a 255 LPH Walbro pump delivers steady, dependable fuel flow to support up to 550 horsepower for high-performance applications. The pump's calibrated output ensures that even under wide open throttle, the system maintains consistent pressure to the rail, reducing the risk of lean conditions. A dedicated in-tank assembly positions the pickup in optimal location for maximum fuel draw, extending pump life and enhancing response.
Tailored Fitment for F-Body Models
This kit offers precise compatibility with 1970-1973 Camaro and Firebird F-body chassis, eliminating the need for generic adapters or cut- and-weld modifications. The tank is contoured to clear frame rails and rear suspension components, while factory bolt locations ensure a direct replacement for stock units. This tailored approach reduces installation time and provides a seamless transition for LS engine swap projects.
Durability and Seal Integrity
Constructed with corrosion-resistant materials and secured by stainless steel straps, the assembly withstands road salt and track use without degradation. O ring seals at each junction guard against leaks and environmental ingress, maintaining system integrity through temperature cycles. The robust construction provides long-term reliability and supports high duty cycles, making it ideal for daily drivers, weekend cruisers and competitive applications alike.
