1971-1972 Buick Skylark A-Body LS and LT EFI Fuel Tank Kit
Fitting an LS or LT powerplant into a 1971 1972 Skylark A-Body brings fuel delivery hurdles and tight clearance concerns that require a targeted fix so we engineered the 1971 1972 Skylark EFI Fuel Tank Kit with a 400 LPH Walbro pump and notched profile. Its low profile shape maintains rear tire and exhaust pipe clearance without altering factory sheet metal and preserves full suspension travel. By housing the pump and level sensor inside the tank the system cuts down on external fittings and hoses for a cleaner underbody layout. This arrangement delivers steady high volume fuel flow under acceleration braking and cornering to ensure reliable operation in LS and LT swap applications.
Precision Notched Profile Preserves Suspension and Exhaust Clearance
The custom shaped tank profile removes material around the rear axle and exhaust routing to maintain factory sheet metal and body lines. This precise form preserves full suspension travel and ground clearance so you can run larger wheels without trimming or rerouting exhaust components. It solves common fitment issues in classic A body chassis by providing direct clearance for both rear tires and headers. The result is a seamless appearance that respects the vehicle’s original silhouette.
Integrated Pump and Sensor Module Reduces Underbody Clutter
Positioning the fuel pump module and sending unit inside the tank eliminates multiple hoses and external fittings along the frame rails. This arrangement cuts down on leak points while streamlining the overall installation process. Included tank straps, filler neck, vent filter and gaskets work in concert to deliver a true bolt in replacement with minimal fabrication. Even newcomers to engine swaps will appreciate the cleaner layout and simplified assembly steps laid out in the instructions.
High Volume Pump Ensures Stable Fuel Flow for High Output Engines
At the heart of the kit is a 400 LPH Walbro pump engineered to handle forced induction or engines producing over 550 horsepower. Operating submerged in the tank, the rotor and stator assembly stays cooler and resists cavitation under hard acceleration. This ensures a consistent supply of fuel during cornering and heavy braking so your engine never runs lean. Tuners can confidently push performance limits knowing the system will maintain stable pressure and flow from the first lap to the last.
