1964-1967 Buick Skylark LS and LT EFI Fuel Tank Kit
When installing an LS or LT engine in a 1964-1967 Buick Skylark, achieving consistent fuel pressure becomes critical and this Fuel Tank Kit equipped with a Walbro 400 LPH pump solves that challenge. By integrating the pump inside the original tank casing it reduces the risk of vapor lock under hard acceleration. The kit retains factory mounting points and the stock filler location so body modifications are not required. A calibrated level sender ties into the existing gauge harness to keep fuel readings precise while factory straps, gaskets and a vent filter complete a straightforward installation.
Seamless Tank Integration for 1964 to 1967 Buick Skylark
This fuel tank kit transforms the original reservoir into a modern fuel delivery system without altering the classic body panels. By using all factory mounting points and maintaining the stock filler location, the installation requires no cutting or welding of the chassis. The in tank module sits neatly within the existing cavity, preserving the car's low stance and smooth profile. Technicians will appreciate how the kit follows the original spacing and bolt patterns, allowing the updated tank to fit exactly where the factory unit lived for decades. The result is a restoration that looks period correct but performs to contemporary standards.
Reliable Fuel Delivery with 400 LPH Walbro Pump
At the heart of this kit lies a Walbro pump rated at 400 liters per hour, chosen specifically to handle engines that exceed five hundred fifty horsepower or operate with forced induction. Submerged operation reduces the chance of vapor lock during spirited driving or track use, while the pump's robust design maintains stable pressure under heavy fuel draw. Locating the pump inside the tank also minimizes turbulence in the feed line, yielding more consistent flow at high engine speeds. Whether cruising or accelerating hard, this configuration ensures uninterrupted fuel supply and steady throttle response.
Precision Sending Unit for Accurate Gauge Readings
The supplied fuel level sender interfaces directly with the existing dashboard harness to provide reliable tank readings across the full volume range. Its calibrated float arm is shaped to match the internal contours of the Skylark tank, eliminating the common dead spots that can confuse standard gauges. OE style electrical connectors allow plug and play installation, removing the need for splices or adapters. As a result, the driver retains full confidence in the fuel gauge's accuracy without sacrificing the vehicle's classic interior aesthetics.
Comprehensive OEM Style Hardware for Leak Free Fitment
Every strap, gasket, vent filter and filler neck in this kit is crafted to match the original Buick specifications, simplifying assembly and eliminating guesswork. The tank straps line up precisely with the factory frame points, while molded gaskets form a secure seal that resists fuel seepage. A period correct vent filter safeguards against debris entering the system and maintains proper tank ventilation during operation. By including all necessary components, this kit lets installers avoid last minute parts runs and complete the swap with confidence in both fit and function.
