1971-1972 Buick Skylark A-Body LS Notched EFI Fuel Tank Kit with 255 LPH Pump
When fitting an LS or LT series engine into a 1971 to 1972 Buick Skylark A Body chassis, this EFI fuel tank kit addresses underbody clearance challenges without altering ride height. The notched shell features precision cut recesses that trace LS and LT exhaust manifolds and tire walls while maintaining full fuel volume. A submerged 255 LPH Walbro pump supplies consistent flow for applications producing up to 550 horsepower. Complete with sending unit, straps, filler neck, vent filter, gaskets and hardware, every component is tested for fit on factory openings. For fuel demands above 550 horsepower use a 400 LPH pump kit.
Notched Tank Design for Enhanced Clearance
The 1971-1972 Skylark EFI Fuel Tank Kit features a notched shape that carves away material where the rear axle tube passes nearest the tank surface. This precision cut allows larger tire profiles and smoother exhaust routing without risk of contact or abrasion. CNC formed contours maintain the original volume while improving chassis fit; reinforcing plates weld over the notch to retain structural integrity. The result is a tank that fits flush with the A Body frame rails and requires minimal modification for installation. Each unit is pressure tested to confirm leak free operation and consistent structural performance under road conditions.
Robust Fuel Delivery Supporting Up to 550 Horsepower
A 255 LPH Walbro high-flow pump integrated within the tank ensures steady fuel supply under heavy loads. Designed to support engines delivering up to 550 horsepower, the pump maintains consistent pressure even during rapid throttle transitions and high cornering forces. Bench validation includes extended run time at elevated temperature to replicate heat soak conditions, preventing vapor lock in real world driving. The internal pickup and anti vortex basket deliver clear paths for fuel to reach the inlet, reducing cavitation risk on steep inclines or hard acceleration.
Optimized Compatibility with LS and LT Engine Configurations
Engineered specifically for EFI conversion on classic A Body chassis, this tank kit is fully compatible with LS and LT engines. Integration with MuscleRods mounting solutions delivers exact engine placement and correct drivetrain angles, limiting vibration and premature wear. The kit includes precision matched straps and gaskets molded in fuel resistant elastomer to seal gaps and block contamination. Complete hardware and detailed instructions allow a seamless retrofit without cutting frame rails or fabricating brackets. All components undergo bench and vehicle evaluation to guarantee fit and durability in restoration and performance applications.
