EFI Fuel Tank Kit for 1978-1987 Buick Regal/Grand National LS Swaps
When fitting an LS engine into your 1978-1987 Buick Regal or Grand National, maintaining steady fuel flow often becomes the biggest challenge. This EFI fuel tank kit combines a custom fit tank, an in tank module and a 255 LPH Walbro pump to deliver consistent pressure under heavy load. Components align directly with the Regal's factory mount points to prevent vapor lock and support dependable performance on every drive. Designed to handle up to 550 horsepower, it keeps your vintage muscle car running smoothly under any condition.
Custom Fit Design for Buick Regal EFI Conversions
The fuel tank kit is crafted to align precisely with the factory mounting points on 1978-1987 Buick Regal and Grand National chassis, enabling easy installation without modification to existing frame rails. This exact fit eliminates the risk of vapor lock by positioning the pump module to maintain constant fuel circulation even during hard cornering or acceleration. Engineers matched the tank shape to the G-Body profile, preserving ground clearance and preventing interference with brake or suspension components. As a result, enthusiasts achieve a clean, factory-style installation that supports consistent EFI performance.
In Tank Module and 255 LPH Pump Performance
The integrated in tank module keeps the 255 LPH Walbro pump fully submerged to reduce aeration and ensure uninterrupted fuel delivery under intense demand. Its design responds instantly to throttle changes, maintaining stable pressure for LS engines up to 550 horsepower without drop-offs. By locating the pump inside the tank, heat soak is minimized and pump lifespan is extended, even when pushing the engine to its limits. This combination of module and pump delivers the reliable flow needed for spirited driving or track use.
Durable Construction for Demanding Driving Conditions
Built from high grade materials, the tank resists corrosion and vibration that can compromise fuel system integrity over time. Critical components such as the sending unit, filler neck, and gaskets are engineered to withstand heat cycling and road shock without deformation or leaks. The inclusion of a heavy duty vent filter and robust hardware ensures the entire assembly remains sealed and functionally sound. This emphasis on strength and resilience translates to confidence in every drive, whether on daily routes or at the strip.
