EFI Fuel Tank Kit with 255 LPH Pump for 1971-1972 Chevy El Camino LS Swap
When fitting an LS engine into your 1971 or 1972 Chevy El Camino A Body chassis, reliable fuel delivery from inside the tank becomes a critical concern. This precise EFI fuel tank kit with 255 LPH pump solves fuel starvation by matching factory mounting points and contours for a drop in install with no cutting or welding. Complete with gaskets, straps, a sending unit and step by step instructions, it ensures consistent rail pressure under heavy throttle and preserves the classic underbody profile. Its internal filter keeps debris from reaching the pump motor and guards against vapor lock during sustained cornering or wide open throttle runs.
Custom Contours for Direct Replacement on 1971 1972 El Camino
Every tank in this EFI fuel system kit is precision molded to replicate the underbody profile of the 1971 and 1972 Chevrolet El Camino A Body chassis. By matching the factory mounting points and frame rails, it removes the need for any cutting or welding, preserving both structural integrity and ground clearance. The sending unit and filler neck align exactly with original openings, and precision cut gaskets form a reliable seal around the flange to prevent leaks. Existing straps and mounting hardware secure the assembly in the stock position, so the vehicle retains its classic appearance while accommodating an LS engine swap. This direct fit design not only speeds installation but also eliminates the risk of misalignment that can lead to fuel leaks or rubbing against suspension components. Enthusiasts can trust that the tank will sit correctly on the first attempt, avoiding time-consuming trial and error during assembly.
High Volume 255 LPH Pump Module for Sustained Engine Demands
At the heart of this kit is a 255 LPH Walbro fuel pump module engineered to support LS engines producing up to 550 horsepower. Its robust design delivers a consistent flow rate even at wide open throttle or during extended cornering, preventing lean spots that can damage injectors or pistons. An integrated strainer captures large particles before they enter the pump, reducing wear on internal components and extending service life. By maintaining stable fuel rail pressure under heavy loads, the unit ensures smooth throttle response and reliable combustion across all RPM ranges. This level of flow capacity also provides headroom for performance modifications, so drivers pursuing future upgrades need not replace the tank or pump. In testing, the module sustained rated output without cavitation, confirming its suitability for spirited street use and occasional track duty.
Integrated Filter System Prevents Contaminant Ingress and Vapor Lock
This kit features a dual filtration approach that keeps both liquid fuel and tank vapors under control. An internal mesh strainer on the pump module catches debris before it can damage motor windings or clog injectors, while the included vent filter regulates air pressure and prevents dirt from entering the tank during operation. Together these elements minimize the risk of vapor lock by allowing trapped gases to escape in a controlled manner, even under sustained lateral loads or rapid throttle transitions. The result is consistent fuel pickup and delivery, eliminating hesitation or momentary stalling when cornering or climbing hills at high engine output. By safeguarding against contamination and pressure spikes, the system promotes long-term engine reliability and preserves injector calibration. Installers benefit from fewer service intervals and reduced risk of costly fuel system troubleshooting down the road.
Complete DIY Kit with Precision Hardware and Step by Step Instructions
Designed for enthusiasts at every skill level, this fuel tank kit arrives with every component needed for a full LS swap upgrade, from the in-tank pump module and sending unit to tank straps, filler neck, vent filter, gaskets and mounting hardware. Clear, step by step instructions guide the installer through each phase of assembly, including recommended torque values to ensure leak free seals and proper alignment. By consolidating all necessary parts into one package, the kit eliminates trips to the parts store and reduces the chance of sourcing incompatible fittings. Whether tackling the project in a home garage or professional shop, users can complete the entire fuel system retrofit in a single session without last-minute modifications. The result is a streamlined workflow and peace of mind that no critical component has been overlooked.
