1970 Buick Skylark EFI Fuel Tank Kit for LS and LT Engine Swaps
When installing an LS or LT engine in a 1970 Buick Skylark, maintaining steady fuel pressure is critical and this EFI fuel tank kit with a 400 LPH pump delivers reliable flow for setups pushing beyond 550 horsepower. The custom tank shell mounts directly to the Skylark chassis and precisely matches original A-Body bolt holes while concealing all fuel lines and wiring for a clean underbody appearance. Immersion of the Walbro pump inside the baffle equipped shell prevents cavitation under high demand and keeps supply consistent during hard acceleration. Every strap fitting, gasket and vent filter is included in the package to guide installers through a straightforward assembly without last minute parts runs and to deliver lasting durability with US made components.
Precision Mountting for Exact A Body Fit
This fuel tank kit is engineered to align flawlessly with the 1970 Buick Skylark A Body frame by matching original bolt hole locations and factory clearances. By eliminating the need for custom brackets or drilled mounting tabs, installers can preserve the vehicle's structural integrity and avoid stress on welded seams. The direct fit design keeps fuel lines and wiring routed neatly along factory paths and reduces the chance of wear from chafing or vibration. With the tank seated precisely in its stock position, underbody ground clearance remains consistent and the classic profile is maintained. This exact alignment also simplifies inspection and routine maintenance, as access points mirror the original layout.
Submerged Walbro Pump Placement for Consistent Flow
At the heart of the assembly is a 400 LPH Walbro pump fully immersed within the baffle equipped tank shell. Keeping the pump covered in fuel ensures it stays cool under demand from engines pushing beyond 550 horsepower and prevents cavitation when throttle openings are wide. This constant submersion helps maintain stable pressure during hard acceleration and steep inclines where fuel slosh might otherwise starve the inlet. The arrangement also reduces heat soak, preserving fuel quality and injector performance during extended runs. Overall, the design delivers the steady output modern EFI systems require without the risk of signal drop or starvation.
Internal Baffle Design to Prevent Fuel Starvation
The custom tank shell incorporates welded baffles that limit fuel movement inside the reservoir and keep the pump inlet covered even in dynamic driving scenarios. These internal partitions reduce slosh during cornering or sudden braking, ensuring the sending unit reads accurately for reliable gauge feedback. By controlling fluid inertia, baffles cut down on noise and vibration as fuel moves within the tank, resulting in a quieter ride and more consistent injection timing. Integrating these features within a shell that retains the original 1970 Skylark outline creates a seamless blend of vintage aesthetics and modern reliability. This attention to internal flow management is critical for high demand EFI conversions.
Comprehensive US Made Hardware for Streamlined Assembly
Every component required for installation comes in one box, including tank straps, filler neck, vent filter, gaskets and all mounting hardware alongside the pump module. Sourcing parts in the United States guarantees consistent quality and fitment, so installers avoid surprise supply runs or mismatched threads. The inclusion of a precision sending unit and properly sized gaskets ensures leak free connections at both the tank and line fittings. Organized packaging and clear component grouping allow technicians to follow a logical sequence from removal to pressure testing without interruption. This level of completeness cuts labor time and gives enthusiasts confidence that every piece meets rigorous construction standards.
