LS Swap Notched EFI Fuel Tank Kit with 255 LPH Pump for 1971-1972 Buick Skylark
Installing an LS powerplant into a 1971 to 1972 Buick Skylark often leads to tight fits beneath the chassis, a challenge the 1971 to 1972 Skylark EFI Fuel Tank Kit 255 LPH Pump Notched solves with precision cut recesses carved to clear both exhaust pipes and tire sidewalls without altering the original ride height. Precision notches in the tank shell follow the contours of LS and LT manifolds, preserving full capacity while avoiding interference with frame rails and underbody components. Mounted inside the tank, the 255 liter per hour Walbro pump uses an integrated filter sock and regulator to sustain consistent flow for engines delivering up to 550 horsepower under all driving conditions. Every gasket, mounting strap and vent filter aligns with factory openings on the Skylark chassis to ensure a direct bolt in fit that reduces installation time and retains the classic underbody profile.
Precision Notched Shell for Unmatched Chassis Clearance
The notched tank shell features precisely carved recesses that follow the contours of LS and LT exhaust manifolds to prevent contact with frame rails and wheel wells. By sculpting material only at critical zones, the design maintains full fuel volume and preserves the original ride height of the 1971 to 1972 Skylark. This method avoids interference with tire sidewalls and exhaust pipes without any chassis modifications, protecting both underbody integrity and factory aesthetics. The result is a seamless fit that retains stock capacity and enables enthusiasts to swap modern engines without custom welding or bracket fabrication.
Submerged 255 LPH Pump Ensuring Steady Flow
Housed entirely inside the tank, the 255 liter per hour Walbro pump operates at cooler temperatures under load, vastly reducing the risk of vapor lock and cavitation during spirited driving. An integrated filter sock captures debris before it reaches the regulator, delivering consistent pressure for engines up to 550 horsepower. This arrangement supports precise fuel injection tuning and advanced mapping, while the tank environment shields the pump from road grime and noise. Technicians benefit from a single module that simplifies plumbing and electrical connections compared to external setups with multiple fittings.
Factory Standard Components Simplifying Installation
Every bracket, gasket and mounting strap is tailored to match the Skylark A Body frame attachment points, allowing a direct bolt in assembly that mirrors original GM procedures. The sending unit is preinstalled and wired with a factory standard pigtail for accurate level readings and seamless sensor alignment. Filler neck and vent filter components align perfectly with stock openings to maintain the classic underbody profile without trimming or drilling. Rigorous bench testing of each piece ensures that installers can complete the swap with confidence, reducing garage time and eliminating trial and error.
Comprehensive Support for EFI Conversion on A Body Frames
This tank kit addresses all key plumbing and sensor needs for a modern fuel injection system in a 1971 to 1972 Buick Skylark. By preserving original vent locations and filler neck geometry, it works with OE hoses and clamps for clean evaporation management. The integrated regulator and pump module interfaces smoothly with aftermarket wiring harnesses and engine control units, providing a stable platform for professional tuning. Fitment follows factory specifications so both hobbyists and pro shops can upgrade to EFI without custom fabrication, bridging classic style with modern drivability.
