1964-1967 Chevy El Camino/Wagon EFI Fuel Tank Kit for LS and LT Swaps
When you transplant an LS or LT engine into a 1964 to 1967 Chevy El Camino or Wagon fuel demands rise under hard acceleration and spirited cornering. By placing a Walbro 400 LPH Pump deep inside the factory tank opening you maintain constant pressure and prevent vapor lock even at output levels above 550 horsepower. Installation is straightforward thanks to the complete hardware kit of straps gaskets and filler neck parts that require no tank modifications. Alongside the pump the calibrated sending unit and vent filter work in concert to deliver precise level readings and manage tank pressure for reliable operation on street or track.
Engineered Placement for Reliable Fuel Supply
The Walbro 400 LPH pump module is precisely positioned at the lowest point inside the original tank shell to draw from a fully submerged pickup. This arrangement prevents air pockets during rapid acceleration or sustained cornering forces that are common with engines producing over 550 horsepower. Integrating the pump into the factory opening eliminates the need for custom brackets or welding on the tank, simplifying the fit and alignment. A sealed assembly protects internal components from moisture, debris, and fuel contamination, extending service intervals. By maintaining constant high pressure, the system supports stable injector flow and consistent regulator performance for both daily driving and track events.
Precision Fuel Level Monitoring and Venting Technology
The calibrated sending unit features a multi-point float design that compensates for vehicle roll and pitch, reducing false low fuel warnings during spirited driving. It delivers continuous real-time level feedback so drivers can trust gauge readings under lateral acceleration and rapid directional changes. Working in concert, the vent filter allows air to escape the tank while blocking water, dust, and other contaminants from entering. This balanced approach prevents vacuum formation during highway cruising or city traffic, which could otherwise interrupt fuel flow and lead to vapor lock. Together, the sender and vent filter maintain a neutral pressure environment inside the tank, ensuring steady fuel delivery and engine reliability.
Simplified Drop In Installation for LS and LT Conversions
Specifically tailored to fit 1964 to 1967 Chevy El Camino and Wagon fuel tanks, this kit includes factory style straps, precision molded gaskets, filler neck components, vent filter, and all necessary hardware. Each part aligns seamlessly with existing openings so no tank floor modifications, adapter hoses, or welding are required. Installers drop the complete assembly into the stock opening, tighten fasteners to factory torque values, and simply reconnect the vent hose and electrical leads. The plug and play design cuts installation time and reduces the chance of leaks or alignment errors. Common hand tools are all that's needed to complete a professional-quality swap without fabrication headaches.
American Steel Construction for Ethanol Blend Durability
Manufactured in the USA from corrosion resistant steel, the tank assembly stands up to modern ethanol blend fuels and harsh road conditions without degrading. The heavy gauge metal provides structural rigidity under load and resists deformation over time. Precision molded gaskets are formulated to remain pliable through repeated temperature cycles, ensuring long-lasting leak free seals. Tight production tolerances limit entry points for moisture and contaminants, protecting the pump and sender electronics. By relying on domestic quality control and proven materials, this kit delivers dependable performance and endurance for high-output LS and LT engine conversions.
