1971-1972 Buick Skylark LS EFI Notched Fuel Tank Kit with 255 LPH Pump
Retrofitting an LS engine into a 1971 and 1972 Buick Skylark often runs into tire and exhaust clearance issues, and this notched fuel tank kit with a 255 LPH pump addresses those challenges head on. With its notched tank design, precise recesses carve space for LS and LT manifolds while preserving original ride height and stock chassis geometry without sacrificing fuel capacity. The Walbro 255 LPH pump sits submerged in the tank with an integrated filter sock and regulator to deliver smooth, consistent flow for powerplants up to 550 hp and support modern EFI tuning. Every strap, grommet, gasket, filler neck and vent filter is selected for A-Body frames, aligning with factory locations to simplify assembly and maintain the car's underbody appearance.
Precision Notched Shell for Optimal Clearance
The notched lower tank shell features carefully carved recesses that provide ample room for LS and LT manifolds while maintaining original ride height. By sculpting the tank at key contact areas, this design eliminates interference with tire sidewalls and the exhaust path without any frame alteration. This approach preserves the full fuel capacity of the original unit, ensuring no compromise in driving range. Technicians benefit from a straightforward install process that avoids complex underbody modifications and retains the factory silhouette.
Submerged 255 LPH Walbro Pump for Consistent Flow
Positioned entirely inside the tank, the 255 liter per hour Walbro unit stays cool under heavy load to prevent vapor lock and cavitation during rapid acceleration. The integrated filter sock removes debris before it reaches the regulator, protecting injectors and maintaining peak engine management accuracy. Engine tune-up specialists will appreciate how the internal regulator delivers stable pressure for powerplants up to 550 hp, supporting modern electronic fuel injection mapping. This in-tank configuration ensures reliable performance under varied driving conditions.
Factory-Style Components for Streamlined Installation
Every strap, grommet and gasket in the kit matches the A-Body frame's original attachment points, allowing bolt-in assembly without guesswork. The complete pump module arrives preassembled with sending unit and wiring pigtail to guarantee proper alignment and sensor accuracy. Included filler neck and vent filter adapt precisely to stock openings, preserving the underbody appearance of the 1971-1972 Skylark. Thorough pre-testing of each piece ensures that install times are minimized and fitment is exact.
