1964-1967 Chevy El Camino/Wagon LS and LT EFI Fuel Tank Kit with 400 LPH Pump
Moving an LS or LT engine into a 1964 to 1967 Chevy El Camino or Wagon raises the stakes for fuel delivery and gauge accuracy under load. This 1964 to 1967 El Camino Wagon EFI Fuel Tank Kit 400 LPH Pump positions a Walbro unit inside the original tank opening to maintain steady pressure during hard acceleration and cornering. Along with the pump, the calibrated sending unit and vent filter secure precise fuel level data and guard against vapor lock without any tank modifications. Installation is simplified by the full hardware set of straps, gaskets and filler neck components, while the USA made corrosion resistant steel assembly resists ethanol blend effects for long term durability.
Strategic In Tank Pump Placement for Stable Fuel Delivery
Positioning the Walbro 400 LPH pump module directly at the lowest point inside the original tank ensures uninterrupted fuel supply even under rigorous driving. By drawing from a fully submerged pickup, the system prevents air pockets during hard acceleration or tight cornering, which is critical for engines producing over 550 horsepower or employing forced induction. Integrating the pump within the factory opening removes the need for custom brackets or sheet metal changes. The sealed assembly combines pump, filter and seal in one unit to protect against debris and moisture, extending maintenance intervals and delivering consistent pressure for both street and track applications.
Advanced Sending Unit and Vent Filter Synchronization
The calibrated sending unit provides real time level readings that account for vehicle roll and pitch, reducing false low fuel warnings during spirited maneuvers. Alongside the sender, the vent filter manages tank pressure by allowing air to escape while blocking contaminants. This balanced design prevents vacuum formation under long highway runs or stop and go traffic, avoiding fuel flow interruptions and vapor lock. Together, the precision sender and vent filter maintain a steady environment inside the tank, ensuring the engine receives dependable flow even when lateral forces shift fuel away from the pickup.
Complete Conversion Hardware for LS and LT Installations
This kit includes every component needed for a seamless swap in 1964 to 1967 Chevy El Camino and Wagon fuel tanks. Factory style straps, gaskets and filler neck parts align perfectly with existing openings, eliminating floor pan modifications or adapter hoses. Installers simply drop in the assembly, tighten supplied hardware to factory torque values and reconnect the vent hose and electrical leads. This plug and play approach reduces installation time and minimizes leak risk, allowing builders to focus on engine calibration rather than fabrication.
Corrosion Resistant US Steel Fabrication for Ethanol Durability
Manufactured in the USA from corrosion resistant steel, this fuel tank assembly withstands constant exposure to ethanol blends and road moisture without degrading. Precision molded gaskets resist chemical attack and maintain leak free seals through multiple temperature cycles typical of underbody conditions. Each tank and sender housing undergoes strict quality control to ensure durable performance over years of service. By relying on domestic production standards and in house testing, the kit delivers robust longevity for high output engine conversions and daily driving demands alike.
