Dual LS and LT EFI Fuel Tank Kit for 1970 Buick Skylark
Installing a modern LS or LT engine into a 1970 Buick Skylark demands a fuel supply that keeps pace with aggressive throttle openings and cornering loads, and this 400 LPH EFI tank kit delivers that consistency from day one. It mounts directly to the A-Body frame using original bolt locations and retains factory clearances to preserve chassis geometry and ride height. Every component from the internal baffle system to the fully immersed Walbro pump is engineered to prevent fuel starvation under heavy acceleration or lateral Gs. Installers will appreciate that all straps, gaskets and vent filters are included, allowing a straightforward assembly that matches the tank to the vehicle's original profile.
Precision Fitment for A Body Chassis
The fuel tank is engineered to align exactly with the 1970 Skylark A Body frame by matching original bolt hole locations and factory clearances. This direct fit eliminates the need for custom brackets or modifications, preserving structural integrity and avoiding stress on the frame. Fuel lines and wiring can be routed along the same paths used in 1970, reducing the risk of chafing and vibration wear. With the tank seated in its stock position, ground clearance remains consistent and inspections mirror the original layout. Installers benefit from a seamless integration that maintains the classic underbody profile.
Submerged Pump Configuration for Consistent Flow
At the core of this kit is a 400 LPH Walbro pump fully immersed in the tank's internal cavity. Continuous submersion prevents cavitation under hard acceleration or steep inclines, ensuring the inlet never draws air even in aggressive driving. Immersion also helps cool the pump under sustained demand from engines pushing beyond 550 hp, reducing heat soak and preserving fuel quality. The result is stable pressure and reliable injector performance during spirited runs. This arrangement delivers the smooth, uninterrupted flow modern EFI systems require without risking fuel starvation.
Advanced Internal Baffle Design to Eliminate Slosh
The custom tank shell incorporates strategically placed baffles that control fuel movement inside the reservoir. By limiting liquid inertia during cornering or sudden stops, these partitions keep the pump inlet submerged and maintain accurate readings from the sending unit. Reduced slosh also cuts down on noise and vibration, resulting in quieter operation and more precise injection timing. Integrating the baffle network into a shell that retains the original Skylark outline ensures a factory appearance while delivering modern fluid management essential for high demand engine swaps.
Comprehensive Made in the United States Installation Kit
Every component needed for a complete assembly arrives in one package, including the in-tank pump module, sending unit, straps, filler neck, vent filter, gaskets and mounting hardware. Sourcing each part from manufacturers in the United States guarantees consistent quality, precise fitment and matched thread standards. Organized packaging groups items logically to guide technicians through removal, installation and pressure testing without interruptions or extra supply runs. By supplying every element from straps to seals, the kit reduces labor time and offers installers confidence in a robust, leak free fuel system.
