LS and LT EFI Fuel Tank Kit for 1971-1972 Chevy El Camino
If you are upgrading to an LS or LT engine in a 1971 to 1972 Chevy El Camino, securing dependable fuel flow during aggressive driving is non negotiable and this EFI fuel tank kit with its 400 LPH pump delivers up to 550 hp without risking lean conditions under full throttle. Installation aligns exactly with original A Body mounting points and uses provided straps, filler neck, and gaskets so no custom fabrication is required. The steel tank resists corrosion from road salt and repeated heat cycles while a precision vent filter maintains consistent internal pressure. Together these features ensure each drive runs smoothly whether on the street or at the track.
400 LPH Pump Performance for LS and LT Engines
The heart of this EFI fuel tank kit is a high-efficiency 400 LPH Walbro pump engineered to support LS and LT powerplants up to 550 horsepower. Its precision-matched flow characteristics ensure consistent fuel delivery under heavy throttle and acceleration, effectively preventing lean conditions that can damage components or compromise performance. By supplying ample volume at wide open throttle, the pump maintains a steady pressure rail even when boost or nitrous demands spike, preserving engine reliability. This stable fuel output also contributes to smoother throttle response, reducing hesitation as power requirements change rapidly. For street or track use, that reliability translates directly into more confident driving and sustained power under all load conditions.
Precision-Fit Installation on 1971-1972 A Body El Camino
Every component in the kit is designed to align exactly with the original mounting points on the 1971-1972 Chevy El Camino A Body chassis, eliminating the need for custom modifications. The in-tank pump module, filler neck, tank straps and included gaskets all use existing brackets and hardware, so installation time is minimized and the factory structure remains unaltered. This plug and play approach reduces potential alignment errors and the risk of leaks, allowing installers to focus on other aspects of the LS or LT engine swap. Even those tackling this upgrade for the first time can expect a straightforward process, thanks to clear component fitment and the absence of welding or cutting requirements.
Durable Corrosion Resistant Steel Tank Assembly
Constructed in the United States from robust steel, the fuel tank resists rust and pitting caused by road salt, moisture and repeated heat cycles common in hot underbody environments. The tank's thick gauge walls and heavy-duty straps secure the assembly firmly in place, preventing movement during hard cornering, braking or rough terrain. Internal baffles maintain fuel stability, while external finishes guard against abrasion and corrosion over many seasons. Together, these features offer long term durability and protect the integrity of your fuel system, even in demanding driving scenarios or harsh climates.
Integrated Vent Filter and Sending Unit for Stable Pressure
Maintaining consistent internal pressure is critical for EFI systems, and this kit's precision vent filter ensures balanced airflow within the tank as fuel is drawn out. By preventing vacuum buildup, the vent keeps the pump primed and ready, minimizing cavitation or flow interruptions that could cause surging under load. The included sending unit provides accurate fuel level readings, making it easy to monitor consumption during spirited driving or track sessions. With both components working in concert, throttle response remains sharp and fuel mileage stays optimized, delivering dependable performance mile after mile.
