LS EFI Fuel Tank Kit for 1978-1987 Buick Regal/Grand National
For builders installing an LS engine into a 1978 to 1987 Buick Regal or Grand National, achieving consistent fuel flow under hard throttle is essential and this EFI tank kit handles the task. It contours precisely to the G Body undercarriage and uses factory mount points to preserve brake and suspension clearance. A 255 LPH pump sits submerged inside the steel reservoir, maintaining steady pressure for builds up to 550 horsepower while helping prevent vapor lock. Every component aligns with stock plumbing for a straightforward install that withstands demanding driving conditions.
Custom Contoured Tank for 1978 to 1987 Regal and Grand National
The steel tank is shaped to match the Buick G Body undercarriage from 1978 to 1987 Regal and Grand National models. This precise fit preserves the original brake line clearances and suspension link geometry so no modification of frame rails is needed. By maintaining the factory envelope the fuel system avoids contact with heat sources and road debris, reducing the risk of vapor lock during spirited driving. Installers benefit from a direct bolt in method that streamlines the swap and keeps chassis integrity intact.
Submerged 255 LPH Walbro Pump Module Ensuring Consistent Pressure
Housing the Walbro pump module fully inside the tank prevents air pockets and keeps the unit cooled by surrounding fuel. The 255 liter per hour output supports engine power up to 550 horsepower without pressure fluctuations under heavy throttle. Instant response to throttle inputs helps the injectors deliver the right amount of fuel during rapid load changes on street and strip. Submersion also extends service life by lowering running temperature compared to external pump setups.
Robust Steel Shell with Precision Welds for Enduring Durability
Fabricated from corrosion resistant steel panels the tank shell is assembled with precision welds that stand up to constant vibration and ethanol blends. Integrated reinforcement plates at stress points ensure the structure resists deformation during hard acceleration and braking. A large vent filter and premium gasket set protect against contamination, sealing the system against leaks and maintaining clean fuel over thousands of miles. Each seam is carefully inspected to meet strict tolerance standards, resulting in a reliable reservoir for high demand EFI applications.
Complete EFI Tank Kit for Streamlined LS Swap Installation
This all inclusive kit delivers everything needed for a hassle free installation, from tank straps and filler neck to wiring plugs and hardware. The sending unit and vent filter drop into the factory routing with no adapter modifications required. Each component aligns with stock plumbing to save hours in the garage, letting builders spend more time tuning their LS engines. By packing all parts in one package the kit simplifies planning and reduces shopping for missing fittings.
