1970-1972 Chevelle EFI Fuel Tank Kit with 400 LPH Pump for LS and LT Swaps
Swapping an LS or LT engine into a 1970-1972 Chevelle A-Body demands a tailored fuel delivery solution that maintains pressure during spirited runs and precise fitment under the chassis. The 1970-1972 Chevelle EFI Fuel Tank Kit with 400 LPH Pump addresses this by pairing a CAD engineered flange that mates exactly with original body rails without sheet metal modification and a USA built 400 liter per hour Walbro pump that sustains more than 550 horsepower under sustained wide open throttle. Inside its heavy gauge steel shell internal baffles capture fuel around the pickup tube to prevent air pockets during hard cornering and sudden deceleration. Complete assemblies include the sending unit filler neck vent filter gaskets straps and all installation hardware so underbody appearance remains factory fresh while cutting overall labor steps.
Precision CAD Flange Ensures Exact Chassis Match
This fuel tank kit features a flange assembly engineered with computer aided design to mate precisely with the original 1970 through 1972 Chevelle A Body rails. The exact correspondence with factory mounting points removes the need for sheet metal modification and preserves the vehicle's undercarriage appearance. Maintaining the correct tank pitch also keeps the filler neck aligned to prevent leaks during normal use or spirited driving. Uniform load distribution across the flange reduces stress on mounting straps and assures stability under acceleration, cornering, and heavy braking. The result is a professional fit that honors the Chevelle's classic profile while supporting modern EFI functionality.
American Made 400 LPH Pump for Reliable Delivery
At the heart of this kit is a USA built 400 liter per hour Walbro pump designed to support more than 550 horsepower in supercharged or naturally aspirated configurations. Its precision impeller and integrated pressure regulator deliver a consistent flow even at wide open throttle, preventing lean conditions that can damage engine components. Built to withstand high fuel temperatures and the demands of track or street use, this pump offers stable pressure under sustained WOT runs. Careful quality control during manufacturing ensures durability and quiet operation, making it a dependable choice for high output LS and LT engine swaps.
Networked Baffles Maintain Continuous Fuel Supply
Inside the heavy gauge steel tank, a network of baffle plates and chambers is arranged to trap fuel around the pickup tube during aggressive maneuvers. This internal tank design breaks up wave motion encountered in hard cornering, sudden acceleration, and rapid deceleration, eliminating air pockets that could starve the pump. By controlling fluid movement within the shell, the baffling system ensures a constant fuel supply and stable inlet pressure for the pump. Drivers can count on seamless response whether exiting a tight turn on the street or pushing into the throttle on a closed course.
Complete Kit Saves Time and Preserves Undercarriage Finish
This all inclusive solution bundles the pump module, sending unit, mounting straps, filler neck, vent filter, gaskets, and all necessary hardware into one matched assembly. Builders benefit from a clear installation path that cuts overall labor steps and minimizes parts sourcing errors. Each component is tested as an integrated package to guarantee fitment with factory rails and body contours, preserving the Chevelle's authentic underbody styling. Manufactured in the United States from durable materials and corrosion resistant fittings, this kit delivers lasting service and straightforward maintenance for modern engine upgrades.
