1970-1972 Chevy Chevelle EFI Fuel Tank Kit for LS and LT Swaps
When fitting an LS or LT engine into a 1970 to 1972 Chevrolet Chevelle A Body frame, installers often face interference between the stock tank and exhaust or rear tires. The 1970 to 1972 Chevelle EFI Fuel Tank Kit with a 400 LPH Walbro pump and a notched shell solves this by following factory rail geometry and includes a tank fuel pump module, calibrated sending unit, filler neck, vent filter, gaskets, straps and all installation hardware. Featuring a 400 liter per hour pump rated for supercharged engines or outputs above 550 horsepower, it prevents fuel starvation under aggressive driving. The precision clearance fitment ensures install without altering floor pans.
Notched Tank Architecture
This fuel tank kit is crafted for 1970 through 1972 Chevelle frames with an integrated notch that clears both exhaust headers and oversized rear tires. By routing the tank profile around critical chassis components, the design maintains original suspension travel without interference. This ensures consistent ground clearance even under heavy cornering loads. The notched profile also simplifies installation by aligning directly with stock mounting points.
Fuel Delivery System
At its heart sits a high-flow 400 LPH Walbro pump capable of supporting supercharged or 550+ hp LS and LT engines. This pump delivers steady pressure under sustained wide-open-throttle runs, keeping fuel rails fully primed to prevent starvation. With this level of delivery, drivers experience smooth throttle response regardless of engine output.
Swap Compatibility and Integration
Engineered specifically for LS and LT powerplants, this kit installs directly into 1970 through 1972 Chevelle chassis without alteration. All required fittings and gaskets are included to streamline the swap process, eliminating the need for custom fabrication or guesswork. This focused approach reduces installation time and cost.
Durable Construction and Reliability
The tank shell is formed from corrosion-resistant materials and features reinforced mounting flanges to withstand track and street use. Its robust weld seams and precision leveling resist deformation under repeated thermal cycling. Designed for long service life, this kit delivers dependable performance for both weekend racers and daily drivers.
