1971-1972 Buick Skylark A-Body LS and LT EFI Fuel Tank Kit with 400 LPH Pump
Swapping an LS or LT engine into a 1971-1972 Buick Skylark requires a reliable fuel delivery solution that fits within the A Body chassis without cutting or reshaping the original shell. The 1971-1972 Skylark EFI Fuel Tank Kit with 400 LPH Pump answers this need by combining an in tank pump module in a precisely formed fuel tank that aligns with factory frame rails and mounting points. With a flow rated 400 liter per hour pump built for supercharged or over 550 hp setups, the package includes fuel sending unit, straps, filler neck, vent filter, gaskets and all installation hardware to complete the swap. Technicians will value precise fuel level readings and venting to prevent vapor lock under cornering loads, resulting in a turnkey fuel system that requires no chassis modifications.
Overview of the 1971 to 1972 Skylark EFI Fuel Tank Kit
The 1971 to 1972 Skylark EFI Fuel Tank Kit combines a precision molded fuel tank, a 400 LPH Walbro pump and a complete in tank module for modern engine conversions. Every component is engineered for the 1971 to 1972 Buick Skylark A Body chassis, providing a direct replacement that retains factory mounting points. This kit is optimized for use with GM LS and LT engines, delivering a seamless swap solution and eliminating the need for custom fabrication. Rigorous fitment testing ensures that exhaust clearance and suspension travel remain unrestricted while offering a clear path for fuel delivery under hard acceleration and cornering.
Technical Integration and Fitment
This fuel tank kit works with MuscleRods mounts to maintain precise engine placement and correct drivetrain angles. The design locks into factory channels on the unibody frame rails, preserving ride height and handling characteristics while supporting LS and LT engine swaps. Integrated fuel level sensors provide accurate real time readings on the stock gauge cluster and the venting system uses high flow check valves and breather lines to prevent vapor lock. The custom tank profile follows the original body contour for a seamless underbody fit that retains trunk cargo capacity and prevents interference with rear suspension arcs.
Performance and Reliability
At the heart of this assembly is a 400 LPH Walbro pump rated to feed supercharged and 550+ horsepower engines without pressure drop. The in tank fuel module houses both pump and filter within the tank shell to ensure constant supply under cornering and launch. This arrangement reduces inlet cavitation and heat soak by submerging the pump inlet below the fuel surface. An integrated baffle system stabilizes fuel during hard driving, maintaining pump pickup and preventing fuel slosh that can starve the engine under high G loading.
Construction and Durability
Proudly made in the USA from corrosion resistant steel, this fuel tank kit withstands road salt, moisture and ethanol blends. Precision welds and leak tested seals meet or exceed OEM standards for strength and longevity. All fittings are CNC machined for repeatable fit and performance, and the tank is finished in a chemical resistant coating to guard against environmental damage. This high-performance solution delivers confidence for street rods that see regular use or track duty, backed by a full tank and pump warranty.
