1964-1967 Chevy El Camino/Wagon LS and LT EFI Fuel Tank Kit with 400 LPH Pump
Swapping a high output LS or LT engine into a 1964-1967 Chevy El Camino or Wagon often reveals weak stock fuel systems that cannot keep pace with 550 horsepower demands. This EFI Fuel Tank Kit with a 400 LPH pump tackles that issue by fitting into the factory tank opening for direct compatibility. Engineers built the module around a precision sending unit and secure straps to preserve accurate fuel level readings and prevent vapor lock in spirited driving. With all mounting hardware included and no sheet metal modifications required, the conversion to modern LS and LT power becomes more reliable and straightforward.
Optimized Fuel Delivery for LS LT Swaps
The kit integrates the Walbro 400 LPH pump directly inside the stock tank opening eliminating the need for sheet metal changes. Mounting the pump at the lowest point in the tank ensures consistent draw of fuel under high acceleration and cornering. The 400 litre per hour capacity meets the demands of engines up to 550 hp, supporting boost and extended wide open throttle without pressure drop. By housing the pump within a sealed module, the system prevents air ingestion and maintains reliable flow during spirited driving.
Precision Level Monitoring and Ventilation
The integrated sending unit is calibrated to deliver exact readings on the factory gauge, so you can count on accurate fuel level feedback at all times. A dedicated vent filter allows air to move freely while blocking debris from entering the tank, which prevents vacuum pockets that can lead to vapor lock in demanding conditions. This coordinated sensing and venting strategy keeps your LS or LT power system running smoothly during extended runs and stop go traffic. The result is steady engine performance without unexpected fuel interruptions.
All Inclusive Hardware for Streamlined Installation
Every component needed for the conversion arrives in one box from the pump and sending unit to tank straps, filler neck, gaskets and mounting bolts. The pre matched parts fit the 1964 through 1967 El Camino and Wagon factory opening, so no extra brackets or fittings are required. Engineers included durable straps and seals to ensure a leak free assembly that withstands track and street use. This comprehensive kit reduces assembly time and avoids the hassle of sourcing separate pieces.
Durable Construction Backed by US Manufacturing
This kit is proudly made in the USA using quality materials and proven manufacturing methods to withstand corrosive fuel and road conditions. The robust pump module and hardware deliver lasting durability, while factory style gaskets provide a positive seal against leaks. By choosing a system built to OEM standards, you maintain the structural integrity of your El Camino or Wagon floor pan without compromise. Reliable performance and longevity combine to protect your LS and LT investment mile after mile.
