EFI Fuel Tank Kit for 1970-1972 Chevy Chevelle A-Body LS Swaps
Installing an LS powerplant in a 1970-1972 Chevelle A-Body often creates tight exhaust and suspension interference and this notched EFI tank kit carves critical space while feeding engines up to 550 hp through a 255 LPH pump. By reshaping the lower shell to follow the contour of exhaust pipes and leaf spring hangers the design avoids interference without trimming tubs or fabricating adapters. Consistent pressure under high engine load keeps throttle response sharp and reduces the risk of vapor lock, with direct fit to factory mounts preserving chassis geometry for street or track use.
Optimized Notched Shell For Chevelle A Body Clearance
The lower fuel tank shell features a precisely shaped recess that mirrors the curves of exhaust pipes and leaf spring hangers beneath the Chevelle A Body frame rails. By removing material only in targeted areas, the design preserves the integrity of the factory floor pan and maintains original chassis geometry. This approach eliminates the need for time consuming tub trimming or custom frame adapters, saving hours in the installation process. Maintaining correct ride height and body alignment also protects suspension components and exhaust from contact, even under aggressive driving conditions.
In Tank 255 LPH Pump Module For Stable Fuel Pressure
At the heart of the assembly, the 255 LPH pump sits fully submerged inside the sealed steel shell, where coolant from the fuel prevents overheating and reduces vapor lock risk. Delivering consistent flow to engines rated up to 550 horsepower, it ensures sharp throttle response during rapid acceleration or sudden load changes. Locating the pump in tank simplifies plumbing and improves reliability compared to external setups. The modular module can be removed for maintenance or swapped for a higher capacity unit without dropping the entire fuel system.
Steel Shell With Internal Baffles For Uninterrupted Delivery
Constructed from thick gauge steel, the fuel tank resists deformation from road debris and stands up to chassis flex without leaking. Fully welded seams guarantee a secure seal throughout the shell's life, while internal baffles trap fuel around the pump inlet during hard cornering, braking, or acceleration transitions. This design prevents air pockets from forming at the pickup, maintaining even pressure under all driving conditions. The result is uninterrupted fuel supply, minimized cavitation, and extended pump longevity.
Complete Kit Assembly For Seamless Frame Rail Fitment
Every component needed for a direct fit installation arrives preassembled for factory frame rail mounting. Included are the in-tank pump module, sending unit, filler neck, vent filter, tank straps, gaskets, and all matching hardware for original fuel lines and body openings. Welded locating tabs and precision bracket holes ensure perfect alignment from the start, keeping the tank securely in place. Clear, step by step instructions guide installers to accurate fuel level readings and immediate engine operation without guesswork.
