1970-1972 Chevy Chevelle EFI Fuel Tank Kit for LS and LT Swap
Carving out clearance for modern LS or LT engines in a 1970 to 1972 Chevelle often reveals interference between the stock tank and rear exhaust or wheel assemblies, so this notched EFI fuel tank kit provides a purpose built solution to ensure unobstructed fit and reliable supply. By CNC forming the steel shell to match original frame rails and body contours installers gain a direct mounting pattern without custom metalwork. Its integrated 400 LPH Walbro pump sustains consistent rail pressure under sustained throttle inputs, preventing lean spots in setups up to 550 hp. Complete with sending unit, filler neck, vent filter and mounting hardware, the package streamlines the transformation into an authentic plug and play assembly.
Notched Tank Profile Ensuring Exhaust and Wheel Clearance
The tank shell is CNC formed to mirror the original frame rails of a 1970 to 1972 Chevelle, creating a precise notched contour that navigates around factory exhaust tubes and rear wheel assemblies. This exacting profile eliminates interference without the need for cutting or reshaping sheet metal, preserving the steel's structural integrity. By maintaining proper clearances from heat sources and rotating parts, the design minimizes the risk of fuel vapor lock or abrasion over time. Installers gain a time-saving direct fit that adheres to factory chassis lines, ensuring consistent alignment and a secure mounting surface.
Integrated 400 LPH Walbro Fuel Pump Module for Stable Pressure
At its core, the kit features a 400 LPH Walbro pump capable of sustaining a steady flow in naturally aspirated or boosted LS and LT setups up to 550 horsepower. The pump's internal filter damps noise and traps debris before it reaches the fuel rails, while its motor architecture resists cavitation at low tank levels. This balanced flow curve maintains constant rail pressure during hard acceleration and extended wide-open-throttle events, preventing lean-condition risks that can harm engine components. The result is a reliable delivery system that adapts to spirited street driving or weekend track demands.
Comprehensive Kit Components for Simplified LS and LT Swap
This all-in-one assembly includes the in-tank pump module and sending unit, a formed filler neck, vent filter, precision gaskets, tank straps and mounting hardware. Each element is tailored to mate with the Chevelle's stock body openings and frame mounts, removing the guesswork of fitment and reducing overall installation labor. The vent filter blocks moisture and contaminants from entering the fuel system, while the calibrated sending unit ensures accurate gauge readings at all fill levels. By uniting these components in one package, the kit delivers a genuine plug and play experience that streamlines the swap process.
Heavy Duty Steel Construction with Protective Internal Seal
Fabricated from corrosion resistant steel, the tank withstands both vibrational stress and harsh chemical exposure from ethanol-blended fuels. Precision welded seams reinforce high-stress areas and heavy-gauge tank straps secure the unit to the factory rails under dynamic loads. An internal protective seal coats the steel surfaces to guard against rust and prolong service life, even in climates prone to humidity or road salts. Together, these measures deliver a robust foundation for any performance build, giving enthusiasts confidence in their fuel supply system for years of reliable operation.
