LS and LT EFI Fuel Tank Kit with 400 LPH Pump for 1970-1972 Chevy Chevelle
Fitting a modern LS or LT powerplant into a 1970-1972 A Body Chevelle demands a reliable fuel source that clears exhaust and rear wheels, and this EFI Fuel Tank Kit delivers that precise fit. The precision cut notched tank profile clears factory exhaust tubes and wheel assemblies, eliminating the need for custom sheet metal work. Its integrated 400 LPH pump sustains fuel flow under sustained throttle to prevent lean conditions in builds up to 550 horsepower. Engineered for direct installation on the original frame rails, it simplifies swap projects by matching factory mount points and body contours for a clean, secure assembly.
Precision Notched Tank Shape for Exhaust and Tire Clearance
The fuel tank's CNC-cut notched profile is engineered to clear factory exhaust tubes and rear wheel assemblies without any custom sheet metal alterations. By aligning precisely with the 1970 to 1972 Chevelle frame rails and body contours, it maintains safe distances from heat sources and rotating parts. This direct-fit approach not only cuts installation time but also preserves the tank's structural integrity. Installers benefit from a worry-free fit that mirrors original chassis lines while keeping critical components at proper operating clearances.
Reliable Fuel Supply with Integrated 400 LPH Pump
At its core, the kit features a 400 LPH Walbro pump capable of supporting naturally aspirated and supercharged LS or LT engines up to 550 horsepower. The pump's precise flow curve maintains consistent rail pressure under sustained wide-open throttle, eliminating lean-condition risks. Its motor design resists cavitation at low fuel levels, while the module's internal filter ensures quiet, uninterrupted operation. This dependable delivery system provides peace of mind during spirited acceleration or long track sessions.
Plug and Play Kit Components for Streamlined Swaps
This all-in-one assembly comes with every element needed for an LS or LT engine swap into the Chevelle: the in-tank pump module, sending unit, filler neck, vent filter, gaskets, straps and mounting hardware. Each piece is tailored to mate with the stock frame mounts and body openings, delivering a true plug-and-play experience. The vent filter keeps dirt and moisture out of the fuel system, while the precision sending unit offers reliable level readings. By uniting these components, the kit simplifies installation and removes guesswork.
Corrosion Resistant Steel Structure with Protective Coating
Constructed from corrosion resistant steel and sealed with an internal protective coating, the tank withstands vibrational stress and chemical attack from modern fuel blends. Precision-welded seams provide strength at stress points, while heavy-duty straps secure the assembly to factory rails. This robust build resists rust and flex under hard acceleration or track use, ensuring consistent fuel delivery and long service life. The result is a foundation you can trust for demanding driving conditions.
