1971-1972 Buick Skylark 400 LPH EFI Fuel Tank Kit for LS and LT Swaps
For Skylark A-Body restorations using LS or LT power this fuel tank assembly solves the weak feed issues of the original unit by housing a matched reservoir and a 400 LPH pump within the factory cavity. Technicians will find that the bolt in fit to stock straps mounting gaskets and vent hardware removes any need for chassis modifications and secures the module with millimeter accuracy. The internal module integrates pump filter and level sensor to maintain pressure and to prevent vapor lock during hard cornering or extended acceleration runs. Accurate fuel level readings and stable delivery under heavy load give dash data and engine performance the reliability modern swaps require.
Integrated In Tank Fuel Module Simplifies Plumbing
The all in tank design brings the pump filter and sending unit together in a single assembly, removing the need for multiple lines and fittings under the chassis. With the filter inlet immersed in the reservoir, fuel temperatures remain lower and component wear is reduced over time. Technicians benefit from having one service point when it comes to maintenance or replacement, cutting down diagnosis time and ensuring reliable performance. By consolidating these elements inside the tank, potential leak locations are minimized and fuel delivery remains consistent during spirited driving.
400 LPH Walbro Pump Delivers Stable Flow for 550 HP Demands
At the heart of this kit lies a 400 LPH Walbro unit engineered to support high output LS and LT powerplants up to 550 horsepower or more. Placed inside the tank, the pump operates without cavitation when the vehicle experiences aggressive acceleration or cornering forces. Its compact form fits neatly within the housing to maximize usable fuel volume while still delivering steady flow under sustained demand. Manufactured in the United States under strict quality standards, it provides long term reliability and preserves pressure consistency for performance engines.
Precision Fit to 1971 1972 Skylark A Body Chassis
This fuel tank assembly is molded to replicate the factory cavity of the 1971 and 1972 Skylark A Body, ensuring millimeter perfect alignment with existing frame rails and mounting points. The included straps gaskets and vent hardware match the original layout so no cutting drilling or custom brackets are required. Maintaining stock geometry preserves underbody clearance and allows the use of reusable factory parts to secure the unit. Installers can count on a direct bolt in process that eliminates trial and error and speeds up project timelines.
Complete Kit Contents Ensure Seamless Installation
Every component needed for a full fuel system upgrade is provided in one convenient package. Alongside the 400 LPH pump and in tank module, the kit includes the sending unit filler neck vent filter gaskets straps and all necessary hardware. This comprehensive selection removes the need to source parts separately or adapt mismatched pieces, reducing delays and unforeseen costs. With everything designed to work together, installers achieve a leak free seal correct venting and accurate fuel level readings right out of the box.
