1978-1987 G-Body Regal & Grand National LS Fuel Tank Upgrade

Achieve unwavering fuel pressure under demanding loads in your classic G Body Regal or Grand National thanks to the custom-fit tank and 255 LPH Walbro pump. Engineered to support up to 550 horsepower and constructed from premium materials, it offers precise bolt in installation, prevents vapor lock and optimizes fuel efficiency for consistent throttle response and dependable performance in all driving conditions.

1978-1987 Buick Regal and Grand National LS EFI Fuel Tank Kit

Starting an LS engine swap in a 1978-1987 Buick Regal or Grand National demands a fuel system that maintains steady flow under load and prevents vapor lock through precise G Body integration. Constructed from thick steel with precision welds, it uses original mounting points, preserves brake line routing and suspension geometry and maintains underbody clearance so no frame rail modifications are required. Inside this reservoir a 255 LPH pump remains submerged to provide consistent pressure for engines up to 550 horsepower while eliminating air pockets during rapid throttle changes. Installers value its direct fit to factory fill and vent lines which streamlines plumbing and cuts swap time without adapters.

Precisely Matched Steel Tank Design for G Body Chassis

The steel fuel tank is formed from heavy gauge panels shaped to follow the underbody profile of 1978 to 1987 Buick Regal and Grand National models. This precise contouring preserves original brake line routing and suspension geometry without any frame rail modifications. By hugging the chassis underside, the tank maintains clearance from exhaust heat and road debris, reducing the risk of vapor lock during spirited driving. Installers benefit from a direct bolt in fitment using factory mount points, which minimizes install time and safeguards the vehicle's structural integrity. The result is a seamless integration that respects the original underbody design while delivering modern EFI capabilities.

Efficient Submerged Fuel Pump for Stable Delivery

At its core, the in tank module houses a 255 liter per hour Walbro pump fully immersed in fuel to keep the pump cool and prevent air pocket formation. Submerged operation ensures continuous pressure for LS engines up to 550 horsepower, even under rapid throttle transitions. This arrangement eliminates vapor lock and sustains fuel flow to the injectors for consistent combustion and peak performance. The quiet, sealed design also reduces noise and heat buildup compared to external pump setups, making it suitable for both street use and track sessions. The system speeds fuel delivery response and maintains optimum injector operation across varied driving conditions.

Robust Welded Steel Construction for Lasting Durability

Constructed from high grade steel panels joined by precision welds, the tank resists corrosion and withstands constant vibration and ethanol based fuels. Reinforcement plates at critical stress points prevent deformation during hard acceleration or extreme braking. Each seam undergoes rigorous inspection to maintain tight tolerances and guard against leaks, while a premium vent filter keeps contaminants out of the reservoir. A complete gasket set ensures each junction remains sealed for thousands of miles of trouble free service. Together, these measures deliver a fuel supply system that endures demanding driving conditions without sacrificing reliability.

Complete EFI Fuel System Kit for Streamlined Assembly

This comprehensive kit includes all components needed for an LS EFI conversion in G body Regal and Grand National models, from the in tank pump module and sending unit to tank straps, filler neck, vent filter, gaskets and installation hardware. Every part is designed to match the factory fuel and vent lines, allowing reuse of existing plumbing without the need for adapters. The sending unit plugs directly into the stock wiring harness, and the filler neck seats in the original access opening for a factory correct fit. By bundling all required items, the kit reduces parts sourcing and accelerates installation for a more efficient swap process. This plug and play approach lets builders focus on performance tuning rather than fabrication details.
