1970 Buick Skylark EFI Fuel Tank Kit for LS and LT Engine Swaps
Starting a new LS or LT conversion in your classic A Body demands reliable fuel delivery and precise fit to preserve exhaust and tire clearance. The 1970 Skylark EFI Fuel Tank Kit with 400 LPH pump and notched shell solves those challenges with a laser notched design that retains factory strap holes and mirrors floorpan contours for interference free clearance around exhaust pipes and rear tires. Its removable top mount module isolates a 400 LPH pump and fine mesh sock filter in fuel to prevent heat soak and maintain steady pressure on builds up to 550 horsepower. To simplify installation the kit includes a sending unit, pre bent filler neck and all necessary hardware so integrators can move from frame to first fire without parts shortages.
Laser Notched Tank Shell Following 1970 Skylark Floor Contours
The fuel tank shell is precision cut by laser to mirror the curves of the 1970 Skylark A Body floorpan, ensuring exhaust pipes and rear tire walls remain undisturbed. By retaining the original strap holes, the design preserves structural rigidity under load without forcing installers to reshape frame rails or alter sheet metal. This careful approach guarantees the tank seats flush against factory rails and reduces the risk of rattles or contact during cornering and rough road conditions. The result is a seamless integration that honors the classic chassis geometry while facilitating modern EFI hardware integration.
Submerged 400 LPH Walbro Pump Ensuring Consistent Pressure
At the heart of this kit lies a 400 LPH Walbro fuel pump fully immersed in the tank's internal module, where constant contact with fuel lowers operating temperature and prevents heat soak. A fine mesh sock filter at the inlet captures contaminants before they reach the pump, extending component life and protecting injectors from debris. This arrangement delivers smooth, uninterrupted fuel flow from idle through maximum throttle for powerplants up to 550 horsepower. By housing the pump underwater, the system also benefits from reduced mechanical noise, resulting in a calmer cabin experience during spirited driving or highway cruising.
Removable Top Mount Module for Rapid Service Access
The fuel pump and filter assembly reside in a top mount module designed for easy removal without dropping the tank or disconnecting major plumbing. Technicians can access electrical connectors and fuel lines within the opening, allowing pump swaps or sock filter changes in minutes. This modular layout minimizes fuel spills and trims service time, which is especially valuable in compact underbody compartments. By simplifying routine maintenance tasks, the housing design maintains vehicle uptime and keeps performance dependable over long term use.
Comprehensive Hardware Package Aligned with A Body Factory Points
This kit supplies every piece needed for a turnkey installation, including the sending unit, tank straps, pre bent filler neck, vent filter, gaskets and mounting fasteners. Each component is engineered to lineup with the original factory points on the 1970 Skylark chassis, eliminating last minute trips for missing parts or adapters. By delivering a complete assortment in one package, installers can move directly from test fit to fuel system calibration without interruption. The result is a streamlined conversion process that reduces labor hours and preserves project timelines.
