1970-1973 Camaro/Firebird EFI Fuel Tank Kit with 400 LPH Pump for LS and LT Swaps
For enthusiasts dropping an LS or LT engine into a 1970 through 1973 Camaro or Firebird, maintaining rock solid fuel delivery under high load becomes the top priority. This EFI tank kit relies on a 400 LPH Walbro pump to supply consistent flow even when power levels push past 550 horsepower. Integrated vent filters trap airborne debris before it reaches the module while precision molded O ring seals lock out vapors and prevent leaks. It mounts directly to factory frame rails using purpose built straps and hardware, preserving the original underbody profile and speeding up installation.
Optimal Fuel Delivery from the 400 LPH Walbro Pump
The core of this EFI tank kit is the 400 LPH Walbro pump engineered to sustain engines above 550 horsepower without hesitation. Precision balanced rotors and hardened steel internals maintain consistent fuel pressure through the full rpm range, eliminating starvation during sudden throttle inputs or prolonged high power demand. Stable rail pressure ensures injectors deliver the exact volume needed for precise combustion timing and responsive acceleration. Designers sized the pump with capacity headroom, allowing future power upgrades without swapping to a different unit. This focus on reliable flow under duress translates directly into smoother power delivery and improved driving confidence.
Advanced Filtration and O Ring Seal Protection
Protecting the fuel supply begins with integrated vent filters that trap airborne debris and moisture before it can reach the pump module. At every junction, precision molded O ring seals lock out contaminants and seal in vapors, reducing the risk of leaks and corrosion. This two stage defense keeps pump internals free of abrasive particles, extending the life of steel components and limiting injector fouling. By preventing contamination at its source, maintenance intervals grow longer and overall system dependability improves. Owners can focus on driving rather than frequent checks or premature part replacements.
Seamless LS and LT Swap Integration
This tank kit has been developed specifically for LS and LT powertrain conversions in first generation Camaro and Firebird chassis built between 1970 and 1973. The in-tank pump module and sending unit are oriented for accurate level readings on the stock gauge cluster, so no gauge modifications are required. By matching factory delivery characteristics while accommodating elevated flow demands, injector spray patterns remain consistent across varying load conditions. The result is precise atomization and stable combustion under all driving scenarios. Compatibility with Chevrolet Gen III and Gen V electronics ensures clean integration with existing engine management.
Bolt In Installation Preserving F Body Underbody Profile
Installation follows factory frame rail mounting points using purpose built tank straps and hardware, eliminating the need for cutting, welding or custom brackets. The filler neck, gaskets and sending unit arrive preassembled, allowing a one-stage installation once the stock tank is removed. Clear instructions guide technicians through each step, resulting in a secure fit that resists vibration and maintains original underbody lines. This streamlined process reduces install time and protects the classic chassis appearance beneath the car. Builders gain confidence in both fit and function without sacrificing the vehicle's factory style.
