LS and LT EFI Fuel Tank Kit for 1970 Buick Skylark A-Body
When tackling an LS or LT swap in a 1970 Buick Skylark A Body this EFI fuel tank kit is engineered to preserve exhaust and tire clearance while supplying the high volume needed for builds up to 550 horsepower. Its precision notched shell aligns with factory strap holes and fits the original frame rails without grinding or bending. A removable module houses the 400 LPH pump and fine mesh sock filter to ensure steady pressure and quiet operation. Installers will value the inclusion of a sending unit, pre bent filler neck and all hardware for a streamlined installation and straightforward maintenance.
Precision Notched Shell for Seamless A Body Fitment
The tank shell is laser notched to follow the contours of the 1970 Buick Skylark floorpan, clearing exhaust pipes and rear tire sidewalls with exacting precision. By retaining the original strap holes, the design preserves the frame rail rigidity that is vital under acceleration and cornering loads. This tailored approach removes the need for bending frame rails or trimming sheet metal, allowing installers to rely on a direct fit that honors the classic A Body structure. The notches also ensure the installation mirrors factory geometry, reducing the risk of rattles or interference during daily driving. Overall, this shell transforms a modern EFI pump into a component that coexists naturally within a vintage chassis.
Submerged Fuel Module for Temperature Control and Low Noise
At the heart of the kit lies a 400 LPH Walbro pump housed in a sealed, submerged module that keeps the unit cool and the cabin quiet. Immersing the pump in fuel prevents heat soak, which can degrade performance under sustained high horsepower operation. A fine mesh sock filter on the inlet captures debris before it reaches the pump, protecting injectors and prolonging service life. This configuration delivers steady pressure from idle up to wide open throttle on LS and LT powerplants, ensuring a smooth response whether cruising city streets or pushing hard on the track. The submerged module also dampens mechanical noise, creating a more refined driving experience.
Removable Pump Housing for Rapid Service Access
The pump assembly is contained within a top-mount housing designed for quick extraction, avoiding the need to drop the entire tank for routine maintenance. Technicians can swap out the pump or replace the sock filter in minutes, without disturbing fuel lines or frame components. Electrical connections remain organized inside the module, reducing the chance of wiring damage and keeping installation neat. This modular layout minimizes downtime and spill risk, which is especially valuable in tight underbody environments. By focusing on serviceability, the kit ensures longterm upkeep stays straightforward even as conditions change.
Complete Hardware Package for Hassle Free EFI Swap
This kit brings together every part needed to integrate LS or LT engines into a Skylark fuel system without last-minute trips to the parts store. Included are the 400 LPH Walbro pump module, sending unit, tank straps, pre-bent filler neck, vent filter, gaskets and all required fasteners. Each component is validated for direct alignment with the factory mounting points, so installers can move seamlessly from fitment to fuel tuning. By unifying all elements into one assembly, the package cuts installation time and keeps project schedules on track. Whether building a street cruiser or a weekend warrior, this comprehensive offering removes guesswork and delivers a polished outcome.
