LS/LT EFI Fuel Tank Kit with 400 LPH Pump for 1964-1967 Chevy El Camino/Wagon
The 1964-1967 El Camino/Wagon EFI Fuel Tank Kit with 400 LPH Pump restores reliable fuel flow for high demand LS and LT engine conversions by mounting a Walbro pump inside the factory tank opening. Placing the pump module at the lowest point and pairing it with a precision sending unit ensures consistent pressure under cornering and prevents vapor lock during spirited driving. Installation requires no sheet metal modifications and includes all straps, filler neck parts and seals for a true direct fit that keeps gauge readings accurate and fuel delivery steady. Manufactured in the USA from corrosion resistant materials and factory style gaskets it delivers lasting durability under track or street conditions.
Integrated In Tank Walbro Pump Module
The kit features a Walbro 400 LPH pump mounted inside the factory tank opening for seamless integration with LS and LT engines. Situating the pump at the lowest point in the tank ensures a steady draw of fuel during hard acceleration and tight cornering, eliminating the risk of starvation under high demand. This in tank module design removes the need for any sheet metal alterations and prevents air pockets that can lead to vapor lock. Fully sealed, the pump assembly is shielded from contaminants, extending service life and maintaining consistent flow under all conditions.
Precision Fuel Level Monitoring and Ventilation
A calibrated sending unit delivers exact readings to the factory gauge, giving drivers reliable fuel level feedback and preventing unexpected shortages. The integrated vent filter allows air to escape while blocking debris, maintaining consistent internal pressure and avoiding vacuum formation during extended runs or stop and go traffic. This coordinated approach to sensing and venting keeps the fuel supply uninterrupted and the engine running smoothly in both daily driving and spirited track sessions. By combining precise measurement with efficient ventilation, the system safeguards against pressure fluctuations and vapor lock.
Complete Direct Fit Conversion Kit
Every component needed for the EFI upgrade is included in one comprehensive package, 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 eliminates the need for additional brackets or modifications, drastically reducing installation time. Durable seals and robust mounting bolts secure the entire assembly and prevent leaks over the long haul. With no alterations to the floor pan required, enthusiasts can achieve modern LS and LT performance without fabrication headaches.
American Made Corrosion Resistant Construction
The fuel tank kit is proudly manufactured in the USA using materials selected for their resistance to ethanol blended fuels and road moisture. Factory style gaskets and precision mating surfaces maintain a positive seal against leaks, preserving the integrity of the vehicle's structure over years of service. Rigorous quality control at each stage ensures consistent performance and reliable durability under both street and track conditions. Backed by domestic production standards and dedicated support, this assembly offers peace of mind and lasting value for high output engine conversions.
