1970-1972 Chevy Chevelle LS EFI Fuel Tank Kit with Notched 255 LPH Pump
Fitting an LS powerplant into a 1970-1972 Chevelle A Body often runs into tight exhaust and suspension clearance and this notched fuel tank resolves those pinch points while supplying engines up to 550 hp with steady flow. Its reshaped lower shell matches the curves of exhaust pipes and leaf spring hangers to carve critical space under the frame rails, cutting installer time spent trimming tubs or fabricating adapters. Inside the steel shell a 255 LPH pump holds fuel pressure under sustained high revs and installation on factory mounts maintains chassis geometry for consistent performance on street drives and circuit days.
Precision Notched Shell for Exhaust and Suspension Clearance
The fuel tank lower shell features a carefully shaped recess that follows the contour of exhaust pipes and leaf spring hangers under the 1970 to 1972 Chevelle A Body. By carving away material only where needed the design preserves the factory floor pan shape while avoiding any interference with stock suspension components. This targeted cutout eliminates the need for time consuming tub trimming or custom adapters and ensures original ride height and chassis geometry remain intact. The result is a seamless fit that protects exhaust and suspension from contact damage during spirited driving or street cruising.
Integrated 255 LPH Fuel System Assembly
The assembly centers on a 255 LPH pump housed within the sealed steel shell to deliver steady flow for engines rated up to 550 horsepower. Locating the pump inside the tank keeps it cooler than external setups and reduces the chance of vapor lock at sustained engine speeds. Consistent pressure prevents lean running under load and sharp throttle changes, translating to reliable acceleration on track or street. The modular design also allows quick service or future capacity upgrades without major fuel system disassembly.
Durable Steel Shell with Internal Baffle Design
Constructed from thick gauge steel the fuel tank resists deformation from road debris and protects against corrosion over time. Fully welded seams ensure leak free operation even as the chassis flexes under hard cornering or rough road surfaces. Inside the shell welded baffles trap fuel around the pump inlet to prevent air draw during acceleration or abrupt maneuvers. This baffle system preserves fuel supply under all driving conditions and enhances pump life by reducing cavitation risk.
Comprehensive Kit Simplifies Chevelle A Body EFI Conversion
All required components arrive ready for assembly to factory frame rail mounts and original suspension hangers. The kit includes a sending unit, filler neck, vent filter, tank straps, gaskets and mounting hardware selected to match stock fuel lines and body openings. Welded locating tabs and precision bracket holes deliver a true bolt in installation that cuts fabrication time. Clear instructions guide installers through each step, resulting in accurate fuel level readings and immediate engine operation without guesswork.
