LS EFI Fuel Tank Kit with 255 LPH Pump for 1971-1972 Chevrolet El Camino A Body
If your project centers on an LS swap into a 1971 to 1972 Chevrolet El Camino A Body, the 1971 to 1972 El Camino EFI Fuel Tank Kit with 255 LPH pump delivers precise factory location fitment and reliable fuel supply under demanding conditions. Its molded tank body aligns with original frame rails and mounting points so no cutting or welding is required. At its core, the in tank 255 LPH Walbro pump module rated for engines up to 550 hp works with the included sending unit, tank straps, filler neck, vent filter, gaskets and installation hardware. For outputs above 550 hp a 400 LPH pump is recommended. Clear DIY instructions guide each step, ensuring a consistent flow under heavy acceleration and sustained cornering.
Application Fitment and Compatibility
This fuel tank kit is custom engineered for 1971 to 1972 A Body Chevrolet El Camino models. Every dimension is tailored to match the stock underbody contours and preserve suspension travel without clearance issues. It supports LS engine conversions by aligning fuel line exits and bracket clearances with MuscleRods mounts. This integration ensures correct engine tilt and driveshaft angle, reducing wear on hose ends and eliminating misalignment that can cause vibration. The precise fitment avoids cutting or massaging the frame rail, helps maintain chassis strength and preserves factory mounting points for the fuel sender and straps.
Fuel Delivery System Performance
At the core of the kit is a 255 LPH Walbro pump that supports up to 550 horsepower. This high-flow unit delivers a steady supply of fuel to the rail, preventing starvation during prolonged wide open throttle or steep inclines. The matched pickup tube and sending unit minimize slosh and maintain stable pressure even under cornering or hard acceleration. By ensuring a consistent feed, the system protects LS engine components from lean conditions that can lead to detonation or injector hang. The integrated filter assembly also traps debris before it reaches injectors, extending service intervals and bolstering reliability under track and street use.
Installation and User Experience
Designed with the enthusiast in mind, the kit arrives as a fully complete package: tank, pump assembly, mounting hardware and a comprehensive instruction guide. Color coded connectors and a plug and play wiring loom match factory style plugs and standard LS ECU interfaces. All hardware is provided in stainless finish to resist corrosion, and bracket locations are pre-marked on the tank shell for foolproof alignment. The guide uses clear illustrations and step by step text to walk through tank removal, line routing, electrical connections and leak checks. This user friendly arrangement cuts installation time, reduces trips to specialty parts sources and helps builders of all skill levels achieve a precise, professional result.
