Notched EFI Fuel Tank Kit with 255 LPH Pump for 1971-1972 Buick Skylark LS Swap
Swapping an LS powerplant into a 1971 or 1972 Buick Skylark often encounters tight clearance beneath the chassis and this notched EFI fuel tank kit with a 255 LPH pump solves those challenges at the source. It carves precise recesses in the tank shell to clear exhaust pipes and wheel sidewalls for both LS and LT manifolds while preserving the stock ride height and full fuel capacity. The submerged Walbro unit sits with an integrated filter sock and regulator to maintain steady flow for up to 550 horsepower and support modern engine management. Moreover every gasket, mounting strap and vent filter aligns with factory openings on the Skylark chassis for a direct fit that minimizes installation time and retains the underbody profile.
Precision Notched Shell Optimizing Chassis Clearance
The notched fuel tank shell features precision cut recesses that clear the unique contours of LS and LT exhaust manifolds without altering the factory frame rails. By sculpting material at critical contact zones beneath the chassis, interference with tire sidewalls and the exhaust path is completely eliminated while preserving full pump volume and original ride height. This approach maintains the tank's designed capacity so range and refueling intervals remain unchanged. Installers benefit from a retrofit that upholds the Skylark silhouette and structural integrity with no frame modification required. Overall, the design blends seamlessly into the underbody to preserve the classic look while solving modern clearance challenges.
In Tank 255 LPH Walbro Pump Delivering Consistent Fuel Supply
Submerged fully inside the tank, the 255 liter per hour Walbro pump runs cooler under heavy load to prevent vapor lock and cavitation that can disrupt engine performance. An integrated filter sock captures sediment before it reaches the integrated regulator, ensuring consistent pressure even during rapid throttle transitions. With stable fuel delivery for engines up to 550 horsepower, this in tank arrangement supports advanced mapping strategies and precise tuning of modern electronic fuel injection systems. The enclosed environment also reduces noise and protects the pump from external contaminants, enhancing reliability over countless road miles. Technicians will note the simplicity of a single assembly compared to external setups that require multiple fittings and brackets.
Factory Style Components Streamlining Installation
Every bracket, gasket and mounting strap in the kit is tailored to match the original A Body frame attachment points, enabling a simple bolt in assembly that mirrors factory procedures. The pump module is preassembled with an accurate sending unit and factory style wiring pigtail to deliver precise level readings and hassle free sensor alignment. Included filler neck and vent filter components align perfectly with stock openings, retaining the underbody profile and avoiding unsightly modifications. Each piece undergoes rigorous bench testing to confirm fitment and performance, reducing installation time and eliminating trial and error in the garage. As a result, installers can proceed with confidence that all components will work together from the first bolt to the final road test.
Modern EFI Conversion Support on A Body Platforms
This fuel tank kit is engineered to facilitate full EFI integration on 1971 and 1972 Skylarks, addressing both plumbing and sensor mounting requirements in one package. By preserving factory vent locations and filler neck geometry, it enables the reuse of OE style hoses and clamps along with underbody vent filters for clean evaporation management. The in tank regulator and pump assembly work in concert with aftermarket wiring harnesses and engine management modules, providing a solid platform for tuning shops to dial in performance. Fitment to A Body frames remains true to original factory specifications, ensuring that both engine enthusiasts and professional installers can upgrade systems without custom fabrication. Ultimately, this kit bridges the gap between classic aesthetics and modern fuel injection reliability.
