1971-1972 Buick Skylark LS EFI Notched Fuel Tank Kit with 255 LPH Pump
Installing an LS engine into a 1971-1972 Buick Skylark can create tight spaces under the frame when using a standard tank, and this notched fuel tank kit resolves those conflicts without altering ride height. The design features precision cut recesses that track the contours of LS and LT exhaust manifolds, allowing full fuel volume while keeping the classic underbody profile intact. Inside the shell the 255 LPH pump operates submerged to lower operating temperatures and ward off vapor lock, maintaining steady flow for setups pushing up to 550 horsepower. Mounting straps, gaskets and vent fittings match factory openings on the Skylark chassis so installers can bolt in a complete EFI system with minimal adjustments and retain the car’s factory underbody lines.
Precision Recessed Shell for Exhaust and Wheel Clearance
The notched tank shell features precision cut recesses that follow the contours of LS and LT exhaust manifolds and wheel wells. By sculpting material only at critical zones, it preserves full factory fuel volume while avoiding contact with frame rails and tire sidewalls. This ensures there is no impact on ride height or underbody aesthetics on the 1971 to 1972 Buick Skylark chassis. The design eliminates the need for custom modifications, so enthusiasts can swap modern engines without frame alterations or bracket fabrication.
Submerged 255 LPH Walbro Pump for Reliable Flow Under Load
Installed completely inside the tank, the 255 liter per hour Walbro pump stays immersed to run cooler under heavy demands and reduce the risk of vapor lock and cavitation. An integrated filter sock protects against debris, while the built in regulator supplies consistent pressure for engine outputs up to 550 horsepower. This arrangement not only supports precise fuel injection tuning but also shields the module from road contaminants and noise. Technicians benefit from a single self contained unit that streamlines plumbing and electrical connections compared with external setups.
Factory Matched Straps Gaskets and Sensor Alignment
All mounting straps, gaskets and vent fittings are crafted to match the original openings in the Skylark A Body frame, enabling a direct bolt in installation that mirrors GM assembly procedures. The sending unit arrives preinstalled with a factory standard pigtail for accurate level readings and simple sensor hookup. Filler neck and vent components align perfectly with stock points to preserve underbody lines, eliminating trimming or drilling. Rigorous bench testing of each piece guarantees reliable performance and reduces the potential for fitment errors during installation.
Seamless EFI Conversion on Classic Skylark Chassis
This fuel tank kit addresses every key plumbing and sensor requirement for a modern EFI system in a 1971 to 1972 Buick Skylark, preserving original vent locations and filler neck geometry for proper evaporation control. It interfaces smoothly with aftermarket wiring harnesses and engine control units, creating a stable foundation for professional tuning and mapping. By maintaining factory specification for hose routing and mounting, the kit bridges classic sheet metal lines with modern drivability. Hobbyists and professional shops alike can complete an EFI upgrade without custom fabrication, achieving a blend of vintage appearance and contemporary performance.
