1970-1972 Chevy Chevelle A-Body LS and LT EFI Fuel Tank Kit
Whether you're tackling an LS or LT engine swap in a 1970-1972 Chevelle A-Body or building a power focused street machine, the 1970-1972 Chevelle EFI Fuel Tank Kit - 400 LPH Pump delivers the precise solution for your fuel system demands. Engineered to integrate with factory mounting rails, the CAD shaped flange aligns precisely with the A-Body undercarriage and maintains correct tank angle for leak free connections. A USA built fuel pump module rated at 400 LPH Walbro pump supports over 550 hp while advanced baffling prevents fuel starvation under hard cornering. Complete with sending unit, tank straps, filler neck, vent filter, gaskets, and hardware, installation follows a precise path that preserves factory undercarriage geometry and original appearance.
Precision Fit for 1970-1972 Chevelles
This EFI fuel tank kit is custom engineered for direct installation in 1970 through 1972 Chevelle A-Body frames. Each tank shell matches the original mounting points to preserve factory clearances and body panel alignment. By maintaining the stock mounting geometry, it eliminates the need for frame grinding or filler panels, ensuring an accurate fit from the first bolt. The quality steel shell is finished with a durable protective coating to resist corrosion in every environment.
Reliable Fuel Flow Under Pressure
At its core, a 400 liter per hour Walbro fuel pump delivers a consistent supply of fuel to support over 550 horsepower, even with forced induction. This high-performance pump maintains stable pressure under sustained load, minimizing the risk of lean conditions during high rpm or full throttle operation. Internal baffling inside the tank prevents fuel migration under hard cornering, rapid acceleration, or sudden braking. As a result, fluctuations in fuel pickup are eliminated, guaranteeing uninterrupted flow to the fuel rails and injectors under demanding driving conditions.
Engine Swap Integration and Compliance
Designed specifically for LS and LT engine conversions, this kit works in concert with MuscleRods mounts to secure ideal engine placement and correct drivetrain angles. The careful alignment reduces stress on driveline components and transmission bell housing interfaces. All components meet or exceed SAE standards for strength and durability, and every unit is proudly manufactured in the United States. Installation hardware and detailed instructions are included to streamline the process for professional shops and dedicated home builders alike.
