EFI Fuel Tank Kit with 255 LPH Pump for 1971-1972 Chevy El Camino LS Swap
For LS installations in 1971-1972 El Camino models, the EFI Fuel Tank Kit with 255 LPH pump delivers a constant stream of fuel that supports engines up to 550 hp without interruption. Designed for the A-Body undercarriage, each component aligns with original mounting points so you can skip cutting or welding and preserve the factory profile. The complete package includes pump, sending unit, gaskets, vent filter, straps and all hardware, with step by step instructions that guide any skill level through every stage. By maintaining steady fuel flow under heavy throttle and during sharp cornering intervals, this kit prevents starvation and hesitation when your LS engine demands more.
Reliable Fuel Flow with 255 LPH Walbro Pump
The heart of this kit is a 255 LPH Walbro module engineered to support LS engines up to 550 horsepower without interruption. By delivering a steady volume of fuel under rapid acceleration and sustained corner exits, it prevents pressure drop and lean spots that can cause hesitation or engine damage. Internal filtration keeps debris from reaching the pump motor, enhancing durability and quiet operation inside the tank. This level of consistency safeguards fuel pressure for modern LS fuel rails and ensures smooth throttle response in every driving condition.
Exact Fit for 1971-1972 A Body El Camino
Each component in this kit is designed to match the contours and mounting points of the original El Camino underbody. The sending unit and filler neck align directly with stock openings while precision cut gaskets provide a leak free seal without trimming or welding. The system uses factory straps and fasteners to preserve the classic underfloor profile and eliminate the need for custom brackets. By maintaining the original fuel tank footprint, installation is faster and retains the vehicle's factory appearance.
Comprehensive Kit Components Streamline Installation
This all inclusive package delivers every part required for a complete fuel system upgrade. In tank pump module, sending unit, vent filter, filler neck, straps, gaskets and hardware are included along with clear step by step instructions. Detailed guidance covers torque values and sequence of assembly to ensure a tight seal and proper alignment with no guesswork. Even installers with limited experience can follow the manual and finish the swap in a single session without sourcing additional fittings or adapters.
Tuned for LS Fuel Injection Demands
Classic fuel tanks often struggle to meet the flow and pressure requirements of modern electronic injection. This kit upgrades your El Camino with a calibrated sending unit and high capacity pump that maintain correct pressure levels for LS fuel rails. By reducing the risk of vapor lock and preventing aeration inside the tank, it keeps fuel temperature consistent and avoids cavitation under intense throttle input. The result is reliable performance, precise fuel metering and enhanced driveability for your LS swap.
