LS and LT Engine EFI Fuel Tank Kit for 1964-1967 Buick Skylark
Swapping an LS or LT powerplant into a first generation Skylark often hinges on securing stable fuel pressure during spirited runs. This EFI fuel tank kit solves that by fitting a Walbro 400 LPH pump inside the original reservoir while preserving every factory mounting point and stock filler location. A calibrated level sender ties directly into the existing gauge harness to maintain accurate fuel readings across the full tank capacity. Complete gaskets, straps and a vent filter arrive ready to install so classic lines remain intact while delivering reliable flow for high horsepower or forced induction setups.
Classic Tank Conversion Preserves Skylark Aesthetics
By retaining every factory mounting point and the original filler location, the kit transforms the stock reservoir into a modern fuel delivery unit without altering body panels. The internal module slips directly into the existing cavity, ensuring that the car's low stance and smooth profile remain intact. Technicians find that the bolt patterns and clearance match the Buick's original design, so no cutting or welding is required during installation. This approach lets builders enjoy updated functionality while keeping the vehicle's period correct appearance intact.
400 LPH Walbro Pump Ensures Consistent Fuel Pressure
The included pump delivers 400 liters per hour to support engines that exceed five hundred fifty horsepower or run on forced induction. Mounted inside the tank, the pump stays submerged to reduce the risk of vapor lock during hard acceleration or sustained track runs. This configuration also minimizes turbulence, providing a steady flow at high engine speeds and stable pressure under heavy fuel demand. The result is reliable performance whether you are cruising or pushing the engine to its limits.
Calibrated Sending Unit Maintains Gauge Precision
The fuel level sender is shaped to match the internal contours of the Buick tank, eliminating the common dead spots that can confuse ordinary gauges. Its calibrated float arm interfaces directly with the factory wiring harness, offering a plug and play experience without the need for splices or adapters. That direct integration preserves the dashboard layout and ensures that readouts remain accurate across the entire fuel range. Drivers can trust their gauge and plan fueling stops with confidence.
Factory Hardware Delivers Secure Seal and Ventilation
Every strap, gasket and vent filter in the kit meets the original Buick specifications to ensure a precise fit and secure seal. The tank straps align with the frame's factory points, while the molded gaskets resist fuel seepage under all conditions. A period correct vent filter safeguards against debris entry and maintains proper tank ventilation during operation. By including gaskets, filler neck components and all necessary fasteners, the kit streamlines the installation process and avoids last minute trips for missing parts.
