1964-1967 Chevy El Camino/Wagon EFI Fuel Tank Kit for LS and LT Swaps
When swapping a 1964-1967 Chevy El Camino or Wagon to LS or LT power, delivering consistent fuel flow can make or break your build. The 1964-1967 El Camino/Wagon EFI Fuel Tank Kit - 400 LPH Pump ensures a steady supply under 550 horsepower loads by integrating the Walbro 400 LPH pump directly into the tank. Built around a precision sending unit and sealed straps, the assembly keeps fuel level readings accurate and prevents vapor lock in demanding conditions. Installation fits the stock opening and secures with included hardware, making LS and LT conversions more straightforward and reliable.
Seamless In Tank Pump Integration
This fuel tank kit houses the Walbro pump directly inside the tank using a dedicated module that aligns with the factory opening. That design eliminates the need for additional cutting or sheet metal modifications, preserving the original floor pan structure. By positioning the pump at the lowest point, it draws from every drop of fuel and prevents air ingestion during hard acceleration or cornering. Included straps and gaskets ensure a leak free seal, while the preconfigured hardware speeds up the installation process for El Camino and Wagon swaps.
Walbro 400 LPH Pump Supporting Supercharged Power
The heart of this kit is the Walbro 400 LPH unit, capable of feeding supercharged or over 550 horsepower LS and LT engines without breaking a sweat. Its precision rotor assembly maintains consistent flow under heavy load and elevated fuel temperatures, giving you reliable pressure at wide open throttle. This capacity translates to sharper throttle response and smooth power delivery across the entire rev band. Whether you're drag racing or cruising, the pump stands up to sustained high demand.
Accurate Fuel Level Monitoring and Vapor Prevention
A calibrated sending unit provides precise tank level readings, so you never face surprise runouts on the road. Complementing this sensor, an efficient vent filter allows air to enter and exit the tank freely while keeping contaminants out of the fuel system. Proper venting prevents vacuum pockets that can lead to vapor lock when the engine is under continuous strain. The combined result is a rock solid fuel supply and consistent engine operation in all driving conditions.
Complete Conversion Kit Engineered for LS and LT Swaps
This all in one solution delivers every component needed for a clean 1964 through 1967 El Camino or Wagon EFI conversion. From the in tank pump module, sending unit and vent filter to the filler neck, tank straps, gaskets and mounting hardware, each piece is tailored for a direct fit. Pre matched parts reduce assembly time and ensure leak proof connections without chasing extra fittings. Proudly made in the USA, the kit brings durable craftsmanship that stands up to road and track use.
