1970 Buick Skylark EFI Fuel Tank Kit for LS and LT Swaps
If you are converting a 1970 Buick Skylark to LS or LT power, this EFI fuel tank kit delivers the flow and pressure needed for engines pushing beyond 550 horsepower. The design drops into the original bolt pattern on the A Body frame and uses factory mounts to preserve chassis geometry and ground clearance while fitting a fully immersed 400 LPH pump within internal baffles that prevent cavitation during hard cornering or steep inclines. Installation is streamlined by a comprehensive parts set that includes straps gaskets vent filters and mounting brackets all sourced in the US to ensure a direct fit and reliable operation with either LS or LT engines.
Seamless Compatibility with LS and LT Powertrains
This EFI fuel tank kit has been engineered to integrate smoothly with both LS and LT engine configurations in a 1970 Buick Skylark. By maintaining the original A Body frame mounting pattern, it supports a wide range of engine weights and torque characteristics without altering chassis geometry or ground clearance. The design accommodates fuel line routing and wiring paths used by factory systems, ensuring that fuel delivery components remain protected and out of harm's way. Whether you choose an LS crate motor or an LT supercharged package, this kit removes guesswork during conversion and delivers predictable performance at every stage of operation.
Fully Immersed 400 LPH Pump for Cavitation Resistance
At the core of the system is a 400 LPH pump that stays completely submerged within the tank to eliminate air ingestion under high lateral loads. Immersion prevents cavitation during sharp cornering, steep inclines or hard acceleration by keeping the inlet port beneath the liquid surface at all times. Continuous fuel contact also acts as a cooling medium, reducing heat soak when supplying modern engines that demand high flow rates. As a result, drivers experience stable fuel pressure and consistent injector performance even when pushing beyond 550 horsepower.
Advanced Internal Baffles for Fuel Control under Load
The internal baffle network consists of welded partitions that manage fuel movement during quick direction changes or sudden stops. By restricting liquid surge, the system keeps the pump inlet properly flooded and prevents low-pressure events that could lead to engine hesitation. These partitions also dampen slosh noise and ensure accurate level readings from the sending unit. All of this occurs within a tank shell that retains the classic Buick profile, blending authentic underbody styling with modern fluid management.
Complete US Made Kit for Effortless Installation
This all-inclusive assembly package arrives with every strap, gasket, vent filter and bracket needed for a direct assembly in the original bolt locations. All components are manufactured in the United States to precise standards, which guarantees thread compatibility and reliable sealing. The logical grouping of parts guides installers step by step, eliminating extra trips to the parts store and reducing assembly time. With this comprehensive kit, technicians can complete the swap confidently, knowing the fuel system will function leak free and deliver repeatable results.
