1971-1972 Buick Skylark A-Body LS and LT EFI Fuel Tank Kit
When installing an LS or LT engine into a 1971 or 1972 Buick Skylark A-Body the tight frame rails and exhaust routing often clash with stock fuel tanks making secure fuel delivery difficult. This notched EFI tank kit integrates a 400 LPH Walbro pump in a sculpted shell that clears exhaust pipes and rear tires without altering factory sheet metal. Encasing the pump and level sensor inside the tank reduces external hoses and fittings leaving a cleaner underchassis layout and cutting installation time. With LS and LT compatibility engineered into its contours this solution ensures reliable fuel supply for forced induction or 550 hp applications while preserving suspension travel.
Custom Notched Tank Profile for Exhaust and Tire Clearance
The precision sculpted tank contours remove material around the rear axle and routed exhaust path, delivering vital clearance without trimming any factory sheet metal. This approach preserves original chassis rails and maintains full suspension travel, even under heavy loads or sharp impacts. By following the natural lines of the Skylark A Body undercarriage, the design integrates seamlessly and avoids contact with tire sidewalls or hot headers. The result is a worry free installation that retains the classic underbody appearance and prevents interference during spirited driving.
High Output 400 LPH Walbro Pump Performance
Equipped with a 400 LPH Walbro pump, this kit meets the demanding fuel requirements of engines making over 550 horsepower or featuring forced induction. Immersed in fuel, the rotor assembly remains cool and resists cavitation during rapid acceleration, cornering, or braking. This submerged operation ensures consistent flow and stable pressure across a wide range of speeds and throttle positions. Builders can trust the pump to support spirited street use or track duties without risking lean conditions under load.
Integrated In Tank Pump Module Simplifies Underbody Layout
By housing both the pump and the fuel level sending unit inside the tank, this kit eliminates multiple external hoses, fittings, and mounting brackets along the frame rails. Fewer connections reduce potential leak points and make the undercarriage easier to inspect and service. Technicians benefit from a cleaner installation area with minimal clutter, streamlining wiring and plumbing tasks. This integrated solution also lowers the risk of damage from road debris, preserving component life over years of operation.
Streamlined Installation with Complete Kit Components
This all inclusive package supplies every part needed for a true bolt in replacement: tank straps, filler neck, vent filter, gaskets and all necessary hardware. Detailed instructions guide installers through mounting the tank, wiring the pump module and plumbing the fuel lines with minimal fabrication. The accurate sending unit provides dependable fuel level monitoring and prevents unexpected low fuel situations. With all components at hand, shops and hobbyists can complete the swap confidently, reducing vehicle downtime and extra parts sourcing.
