LS-Compatible EFI Fuel Tank Kit for 1964-1967 Buick Skylark
Retrofitting an LS powerplant into a 1964 through 1967 Buick Skylark often exposes the original fuel tank to starvation under hard acceleration and heavy load and this EFI fuel tank kit with a 255 LPH pump addresses that challenge. It mounts using the stock frame hangers and aligns with factory openings to preserve the underbody appearance without any trimming or fabrication. An in tank Walbro pump assembly resists cavitation to maintain steady volume and pressure during spirited runs. Equipped with a calibrated sending unit, it provides accurate fuel level readings under hard cornering and sudden throttle changes, so you can focus on driving on both road and track.
Walbro 255 LPH Pump Assembly for Steady EFI Performance
The in-tank Walbro 255 LPH pump provides the volume required to support LS fuel injection systems up to 550 horsepower without any pressure drop during hard acceleration. Its design maintains constant suction at the inlet to prevent cavitation, ensuring a consistent injector pulse and improved throttle response even under heavy load. Encased in a purpose-built module, the pump remains fully submerged to eliminate vapor lock and extend component life. Enthusiasts will notice stable fuel pressure during spirited driving on street or track, with no sacrifice in reliability over long runs.
OEM Style Installation Preserves Underbody Profile
This fuel tank kit uses the original 1964 to 1967 Skylark frame hangers and factory openings to deliver a truly bolt-in upgrade with no trimming or fabrication required. All tank straps, mounting brackets and gaskets are preformed to match the chassis contours, preserving the classic underbody appearance. A pre-aligned filler neck and precision hardware set streamline the assembly process so builders can complete installation with common hand tools. The result is a clean, factory-correct fit that reduces build time and keeps your Skylark looking authentic.
Calibrated Sending Unit for Accurate Fuel Level Feedback
The integrated sending unit features a precision float arm and sealed housing designed to deliver reliable gauge readings through hard cornering and sudden throttle transitions. Its robust construction resists vibration and contamination, eliminating false low readings or slow gauge drift over time. Drivers benefit from clear, real-time fuel level information that enhances trip planning and avoids unexpected stops. This level of precision builds confidence whether you're tackling winding backroads or pushing for lap times on the track.
American Made Materials for Enduring Durability
Every major component of this kit is crafted in the United States to rigorous quality standards, reflecting a commitment to long-term performance and consistency. The fuel tank body is formed from corrosion-resistant steel, while the pump module, vent filter and sending unit undergo thorough inspection before assembly. Together, these parts withstand daily driving demands and spirited track use without premature wear. Classic Buick owners get a fuel delivery solution that not only meets modern EFI requirements but also stands up to decades of use.
