1964-1967 Chevy El Camino/Wagon EFI Fuel Tank Kit for LS and LT Swaps
When transferring LS or LT power into a 1964-1967 Chevy El Camino or Wagon, reliable fuel delivery and precise gauge feedback become crucial for both street and track use. This EFI fuel tank kit with a 400 LPH Walbro pump mounts directly within the original tank opening to secure steady pressure during hard acceleration and cornering. A calibrated sending unit preserves accurate fuel level readings and stops vapor lock during spirited runs while the complete hardware package of straps seals and filler neck parts eliminates floor pan modifications for a true direct fit. Crafted in the USA from corrosion resistant steel and authentic gaskets this assembly delivers lasting durability even with ethanol blended fuels.
Walbro 400 LPH Pump Module Integration
The core of this EFI fuel tank kit is the high capacity Walbro 400 LPH pump housed directly inside the original tank opening. By positioning the pump at the lowest point in the tank, it maintains consistent fuel draw even during hard acceleration and tight cornering, which is essential for supercharged engines or setups exceeding 550 hp. This in tank module eliminates the risk of air pockets and vapor lock by ensuring the pickup stays submerged under all driving conditions. Since the assembly fits within the factory opening, there is no need for sheet metal alterations or custom brackets. Fully sealed against debris and moisture, the pump module delivers uninterrupted flow and extends service intervals. Installers benefit from a single unit that integrates pump, filter and seal in one precise assembly.
Precise Fuel Level Monitoring and Tank Venting
The calibrated sending unit included in the kit provides exact fuel level readings, sending real time data to the factory gauge and preventing unexpected shortages on both street and track. Its design accounts for vehicle roll and pitch, so fuel slosh under spirited driving will not trigger false low fuel warnings. Alongside the sender, an integrated vent filter allows air to escape while blocking debris, preserving optimal tank pressure and preventing vacuum formation during long highway runs or in stop and go traffic. This balanced approach to sensing and venting helps maintain a stable environment inside the tank, safeguarding against pressure spikes that can disrupt pump performance. The combined sending and venting solution ensures the engine receives consistent fuel flow and delivers reliable performance under all operating scenarios.
Engineered for Direct Fit Installation
Every component required for a straightforward conversion is included in this comprehensive kit, from tank straps and filler neck parts to factory style gaskets and mounting hardware. Pre matched fitment for 1964 through 1967 El Camino and Wagon fuel tanks means there is no need to modify the floor pan or create custom mounts. Installers can simply remove the old components, drop in the new assembly and torque the provided bolts to factory specs. The filler neck aligns perfectly with the original receptacle, and the vent hose and electrical connections plug in without adapters. This approach minimizes installation time, reduces the chance of leaks and lets enthusiasts focus on tuning rather than fabrication. Even first time LS or LT swap builders will appreciate the plug and play nature of the design.
American Made Corrosion Resistant Construction
This fuel tank kit is proudly manufactured in the USA using corrosion resistant steel and precision molded gaskets that resist degradation from ethanol blended fuels and road moisture. Each tank and sender housing undergoes rigorous quality control to ensure leak free seals and consistent performance over years of service. The materials are selected for their ability to withstand constant exposure to chemicals and temperature cycles typical of underbody installations. By relying on domestic production standards and in house testing, the kit offers dependable durability for both daily driving and track use. Backed by comprehensive support, this assembly provides lasting value and peace of mind for high output engine conversions.
