LS and LT EFI Fuel Tank Kit for 1970 Buick Skylark A-Body
This EFI fuel tank kit addresses LS and LT engine swaps in a 1970 Buick Skylark A-Body by supplying a robust 400 LPH pump rated for supercharged packages or engines over 550 hp. Complete with in tank pump module, sending unit, filler neck, vent filter, gaskets, tank straps and installation hardware, it drops into the original tank bay for direct fit. Maintaining factory style steel tank design for electronic fuel injection, this US made assembly integrates with LS and LT powertrains on GM A-Body frames without altering chassis geometry or ground clearance.
Proven Fuel Delivery Performance
The 1970 Skylark EFI Fuel Tank Kit integrates a 400 LPH Walbro pump capable of sustaining fuel demands for power levels above 550 horsepower. This flow rate prevents pressure drop during wide open throttle runs and supports consistent injector operation. Featuring modern EFI compatibility while preserving the 1970 Buick Skylark aesthetic, it bridges vintage appearance with reliable delivery. By matching the original tank contour, it conceals modern hardware behind a familiar silhouette for an authentic appearance. Built in the USA, the pump's precision and material quality uphold pressure stability under track conditions. Stable pressure output contributes to consistent air fuel mixture for precise tuning and engine health.
Precision Fitment for 1970 Buick Skylark
Designed specifically for 1970 Skylark and GM A-Body models, this tank drops in place of the original unit without modification. Compatibility with LS and LT engine configurations is assured, and the included tank straps and installation hardware ensure proper underbody clearance. This ensures correct fuel line routing and optimal orientation relative to the drivetrain, maintaining designed angles for reliable operation and minimizing stress on fittings over time. Bracket integration reduces vibration and secures the tank under lateral loads encountered during spirited cornering. No cutting or welding prevents body integrity issues and retains the original restoration value.
