LS and LT EFI Fuel Tank Kit for 1971-1972 Buick Skylark
When converting a 1971-1972 Buick Skylark to LS or LT power, the stock tank often fails to maintain feed under heavy load and the Skylark EFI Fuel Tank Kit with a 400 LPH pump restores consistent flow to support 550 hp swaps without altering the chassis. Housed in a body matched reservoir, the in tank design keeps pressure steady and prevents vapor lock in sharp turns. Technicians appreciate the direct fit to the factory rails, complete with gaskets, straps and vent parts for an installation focused on engine performance rather than tank modifications. A calibrated sending unit within the assembly delivers accurate level data so dash readings stay reliable during spirited runs.
Seamless Integration with Skylark A Body Chassis
For the 1971 to 1972 A Body platform, the fuel tank housing replicates the factory cavity with millimeter accuracy to eliminate the guesswork of fitment. Every mounting lug, vent port and filler neck position aligns with the original layout, allowing the supplied straps or reusable factory hardware to secure the assembly without modification. Maintaining the stock rail geometry ensures ground clearance and underbody integrity remain unaltered, a key factor when upgrading to modern LS or LT power. This precise contour matching reduces installation time, cuts down on trial fits and avoids the need for custom brackets.
In Tank Module Enhances Efficiency and Reliability
Incorporating the pump, filter and sending unit into a single in tank assembly removes multiple plumbing runs and potential leak points under the chassis. The internal placement keeps the filter inlet bathed in cool fuel, which slows heat soak and extends component life downstream. A precision float sensor within the module delivers accurate level data, maintaining true dash readouts even during hard cornering and acceleration. Integrating these functions simplifies the plumbing layout, reducing installation errors and making routine maintenance easier. Technicians can complete the swap with fewer connections and inspect a single service point when replacing the filter or pump.
400 LPH Walbro Pump for Sustained Engine Demand
As the core of this kit, the 400 LPH Walbro unit sustains flow rates needed for supercharged or high output LS and LT engines targeting 550 horsepower and beyond. By positioning the pump inside the tank, it operates with reduced cavitation risk and maintains stable pressure under sustained acceleration or steep cornering. Its compact footprint fits neatly within the housing to maximize usable volume while still delivering consistent flow. The pump's design resists heat soak common in engine bays, preserving performance consistency. Fully manufactured in the USA, it meets tight quality standards for service life and reliability.
Comprehensive Kit Contents Streamline Installation
This fuel tank kit arrives with every part required for a complete fuel system upgrade, from the 400 LPH pump and sending unit to tank straps, gaskets, filler neck and vent filter. Having these components in one package eliminates scavenging hardware stores and avoids last minute fabrication work. Each part is engineered to work together for a reliable, leak free seal and correct venting function. The dedicated filler neck matches factory routing, preventing kinks or misalignment in the supply line. Overall, the inclusive design minimizes swap downtime and gives installers confidence that no critical element has been overlooked.
