EFI Fuel Tank Kit with 400 LPH Pump for 1970-1973 Camaro/Firebird LS and LT Swap
Swapping an LS or LT engine into a 1970 through 1973 Camaro or Firebird chassis often exposes the stock tank as a weak point when demand spikes and this EFI fuel tank kit with a 400 LPH pump addresses that challenge with consistent delivery under load. Its integrated vent filters and O ring seals stop airborne debris and prevent fuel leaks for reliable operation. Installation uses purpose built straps and hardware that align with factory frame rail mounts on F body models. As a fully assembled system it minimizes installation time and retains the classic underbody appearance.
Consistent Fuel Delivery with 400 LPH Walbro Pump
The core of this EFI fuel tank kit is a 400 LPH Walbro unit calibrated for LS and LT powerplants above 550 horsepower. Its precision-balanced rotors and hardened steel internals sustain uniform pressure across the entire rpm range, eliminating fuel starvation during rapid throttle transitions or extended high load. This uninterrupted volume ensures injectors receive the exact amount of fuel needed for optimal combustion timing and steady power delivery. By maintaining rail pressure under demanding conditions, the pump also leaves headroom for future engine upgrades without requiring a secondary pump change. The result is a stable, predictable supply that enhances throttle response and supports aggressive driving.
Advanced Contamination Defense with Vent Filters and O Ring Seals
Protecting your EFI components starts with the kit's premium vent filters, which trap airborne dust and moisture before they enter the tank. Complemented by precision-molded O ring seals at every junction, the system locks out particulates and seals in vapors, preventing both leaks and corrosion. This two-stage barrier keeps the fuel clean and the pump free from abrasive debris, reducing the risk of injector clogging and early wear. As a consequence, maintenance intervals stretch out and overall fuel system reliability improves. Technicians benefit from fewer service calls, while drivers enjoy consistent performance over long periods.
Plug and Play Underbody Fitment on 1970–1973 F Body Chassis
Installation is simplified by purpose-built tank straps and hardware that align precisely with the factory frame rails of first-generation Camaro and Firebird models. There's no cutting, welding or custom bracket fabrication-each component drops into the stock mounting points for a direct underbody fit. The sending unit, filler neck and gaskets arrive preassembled, enabling a single-stage installation once the original tank is removed. Detailed instructions walk users through module replacement, ensuring a secure, vibration-resistant mounting that preserves the classic undercarriage appearance. This bolt-in approach speeds up the swap process and keeps chassis integrity intact.
