LS EFI Fuel Tank Kit with 255 LPH Pump for 1971-1972 Buick Skylark
If you plan to swap an LS motor into your 1971 and 1972 Buick Skylark, delivering a steady stream of fuel under hard driving is critical and this fuel tank kit directly addresses that need. Beyond fitment, the internal baffling and the 255 LPH Walbro pump work together to tame fuel slosh and sustain flow during cornering or spirited runs. A precision sender aligns with the factory opening to deliver accurate level readings and help avert fuel surprises when pushing the limits on street or track. Installation follows factory tank mounts and uses existing filler locations for a bolt in setup that avoids chassis modifications while the galvanized steel construction and powder coat finish keep corrosion at bay.
Custom Fit Integration for Skylark Frame Rails
The fuel tank kit is shaped to match the original frame rails and filler neck placement of 1971 and 1972 Buick Skylark models, providing a direct bolt in fit without need for cutting or modification. This design uses the factory mounting points so builders can rely on proven chassis locations, eliminating guesswork when aligning the tank. By preserving the original filler position, the kit avoids clearance issues with suspension components and brake lines, saving hours in trial fits. All necessary straps, gaskets and hardware are included to complete the installation in a single session. The result is a streamlined swap that lets you focus on tuning the LS engine rather than custom tank work.
Efficient Pump Cooling and Flow Management
Positioning the 255 liter per hour Walbro pump inside the tank ensures constant immersion in fuel, where natural convection keeps internal temperatures low. This passive cooling effect reduces wear on the motor and extends service intervals compared to external inline units. With capacity rated for engines up to 550 horsepower, the pump maintains stable pressure under sudden throttle changes and long speed passages. Submerged placement also dampens operational noise, delivering a quieter drive. Overall this integration balances performance requirements and reliability in spirited street or track use.
Baffling Design for Consistent Fuel Delivery
Internal baffling channels are engineered to control fuel slosh during cornering, acceleration or braking, directing fluid back to the pump inlet and avoiding momentary starvation. The baffling geometry keeps the pickup submerged even in hard lateral loads, allowing the engine to draw a steady stream of fuel under all conditions. This feature is critical for an LS swap where sudden lean condition could lead to detonation or power loss. By smoothing out pressure variations, the kit helps prevent stumbling during quick transitions. The result is confident throttle response and predictable performance when pushing the limits on track or open road.
Durable Galvanized Steel Shell with Protective Coating
Fabricated from heavy gauge galvanized steel, the tank resists ethanol blends and moisture intrusion that can lead to corrosion in untreated metal parts. A silver powder coat bonds to the pre treated surface to form a uniform barrier against road salts and abrasion while maintaining structural integrity. This coating process protects both the shell and weld seams from long term degradation, requiring only occasional wash down to retain a fresh appearance. Reinforced mounting tabs stand up to vibration and thermal cycles without bending or cracking. The sturdy construction ensures that your fuel system remains reliable for many seasons of driving.
