1970-1972 Chevy Chevelle A-Body LS and LT EFI Fuel Tank Kit with 400 LPH Pump
When fitting an LS or LT motor into your 1970-1972 Chevelle A-Body, you need a fuel tank that ensures steady flow during spirited driving and cornering. This EFI Fuel Tank Kit combines a CAD designed flange assembly that mates perfectly with factory rails and a 400 LPH Walbro pump capable of supporting more than 550 horsepower. Inside the steel shell a network of baffles traps fuel around the pickup to prevent air ingestion under aggressive acceleration and sudden stops. Complete with sending unit, filler neck, vent filter and hardware, the integrated USA made assembly cuts installation steps and preserves the classic underbody appearance.
Precision CAD Engineered Flange Alignment
The fuel tank's flange assembly is modeled using computer aided design specifically for the 1970 through 1972 Chevelle A body rails, delivering exact correspondence with factory mounting points. This precision fit eliminates time consuming trial placements and eliminates any need to modify sheet metal, preserving the stock underbody profile. By maintaining the correct tank pitch, the filler neck stays aligned to prevent leaks and retains the classic stance. Uniform load distribution across the mounting flanges also keeps the assembly stable under acceleration, cornering, and heavy braking.
High Volume Walbro Pump for Consistent Fuel Flow
At the core of this assembly is a 400 liter per hour Walbro fuel pump engineered to support more than 550 horsepower without suffering a drop in delivery rate. Its optimized impeller and integrated pressure regulator ensure a steady stream of fuel even at wide open throttle, preventing lean conditions that can damage engine components. This pump also withstands varying fuel temperatures and repeated operation under demanding driving environments. The result is unwavering performance whether running a mild street cam or a track focused build.
Advanced Internal Baffling to Prevent Fuel Starvation
An in-tank network of baffle plates and chambers stops fuel from sloshing away from the pickup during aggressive maneuvers, keeping the outlet consistently fed. This system breaks up wave motion encountered in hard cornering, rapid acceleration, or sudden stops, eliminating air pockets that cause hesitation or misfires. By controlling internal fluid dynamics, the baffling design delivers continuous pressure to the pump inlet for steady engine response. Drivers experience confidence that fuel will always be available, even under extreme track or street scenarios.
Integrated Kit Design to Simplify Installation
This comprehensive solution combines the fuel pump module, sending unit, mounting straps, filler neck, vent filter, gaskets, and all necessary hardware into one matched package. Builders benefit from reduced parts sourcing and a clear, step-by-step installation path that cuts overall labor time. Every component is tested to work together, ensuring fitment aligns with factory rails and underbody contours. Manufactured in the United States from durable materials and corrosion resistant fittings, the kit supports reliable service and straightforward maintenance.
