LS EFI Fuel Tank Kit for 1971-1972 Chevy El Camino A-Body with 255 LPH Pump
When converting a 1971 or 1972 El Camino to run LS power, reliable fuel delivery inside the stock location is vital. This EFI Fuel Tank Kit for 1971 and 1972 El Camino with 255 LPH pump adapts to the A-Body frame rails and factory mounting points so no cutting or welding is required. With internal filtration and a 255 LPH Walbro module, it maintains consistent flow under hard acceleration and cornering. Complete gaskets, straps, sending unit and detailed instructions guide both garage enthusiasts and professional installers through a clean installation, while the molded tank contours preserve ground clearance and avoid contact with suspension components.
Precision Molded Tank for 1971 1972 El Camino A Body Fit
The tank body is crafted from a single molding that exactly matches the underbody profile of the 1971 and 1972 Chevrolet El Camino A Body chassis. By aligning its contours with the original frame rails and mounting locations, this design removes the need for any cutting or welding and preserves ground clearance for uneven roads and performance driving. The sending unit opening and filler neck sit precisely in the factory positions, and included gaskets seal flawlessly to prevent leaks. Matching the stock footprint also ensures the suspension components and exhaust system remain at factory clearances. This precision fit translates into a faster installation and a reliable, factory style appearance under the vehicle.
255 LPH Walbro Pump Module Delivers Consistent LS Fuel Flow
At its core, the kit features a 255 liter per hour Walbro pump capable of supporting LS engines with up to 550 horsepower output. This high volume delivery keeps fuel rail pressure stable under heavy acceleration or sustained cornering, eliminating the fuel starvation that can lead to lean conditions and engine damage. An internal strainer attached to the pump head captures large particles before they reach the impeller, reducing wear on the motor and preserving performance over thousands of miles. With this capacity built in, the system also provides room for future modifications without requiring an upgrade to the tank or pump. Testing under continuous WOT showed no drop in output or cavitation, confirming reliable operation for spirited street use or occasional track sessions.
Integrated Filtration and Vapor Management for Reliable Delivery
This EFI tank kit employs a two stage filtration approach that protects both pump and injectors from debris while controlling internal tank pressure. A fine mesh filter on the pump module stops sediment from entering the impeller chamber, reducing wear on bearings and extending service intervals. A separate vent filter regulates air exchange as fuel volume changes, preventing dirt intrusion and minimizing the risk of vapor lock during sustained lateral g loads or rapid throttle transitions. By allowing trapped gases to escape in a controlled manner, the system maintains consistent pickup even under high cornering forces. The result is smooth throttle response, fewer interruptions in fuel supply, and a stable operating environment for modern LS fuel injection.
All Inclusive DIY Friendly Kit with Detailed Assembly Guide
This fuel tank package comes complete with every component needed for a full LS swap installation in an El Camino chassis: pump module, sending unit, tank straps, filler neck, vent filter, gaskets and mounting hardware. Step by step instructions lead installers through each phase, from positioning the tank to torquing flange bolts to factory values for leak free seals. By consolidating all parts into one kit, technicians avoid trips to multiple suppliers and eliminate the risk of incompatible fittings. Whether working in a home garage or professional shop, users can complete the retrofit in a single session with confidence that no part has been overlooked. The streamlined process cuts labor time and delivers a professional result that stands up to demanding driving conditions.
