LS EFI Fuel Tank Kit with 255 LPH Pump for 1978-1987 Buick Regal/Grand National
Whether you are swapping an LS into a 1978 to 1987 Buick Regal or Grand National you need a fuel supply solution that fits the chassis without modification and delivers stable pressure under load. This 1978-1987 Buick Regal EFI Fuel Tank Kit with its 255 LPH pump uses the original mounting points brake line routing and underbody clearance to preserve suspension geometry while supporting up to 550 horsepower with minimal risk of vapor lock. Installers appreciate how the custom fit tank and in tank pump module keep plumbing straightforward and reduce bench time before tuning begins.
Custom Fit Integration for G Body Chassis
Custom formed steel tank follows the underbody contours of the 1978 to 1987 Buick Regal and Grand National, using the factory mounting points to maintain the original frame geometry. This precise fit preserves brake line routing and underbody clearance, eliminating the need for frame rail modifications while reducing installation time. By adhering closely to the chassis profile, it also avoids interference with exhaust and suspension components, reducing heat exposure and lowering the chance of fuel vapor formation under load. Installers will appreciate how the direct bolt in design streamlines plumbing without adapters, ensuring a seamless upgrade to electronic fuel injection. The result is an original like installation that supports modern engine performance without altering the classic G body structure.
Submerged Pump Module for Consistent Fuel Delivery
At the heart of this system, a Walbro 255 liter per hour pump remains fully immersed in fuel, which keeps it cool even under sustained high demand. Submerged operation also prevents air pockets and vapor lock, providing consistent pressure to the injector rail for engines up to 550 horsepower. This arrangement delivers faster throttle response and stable operation during rapid acceleration or steep inclines. The sealed design minimizes noise and heat buildup compared to external setups and enhances reliability in street and track conditions. Combined with a premium vent filter, it maintains clean flow to the engine for precise combustion control across all driving scenarios.
Durable Steel Construction for Lasting Reliability
The tank is built from heavy gauge steel panels welded at key stress points to resist deformation during hard acceleration and abrasion from road debris. Each seam goes through quality control to ensure leak free operation under varying temperatures and ethanol blended fuels. Reinforcement plates at the strap mounts protect against fatigue and prevent damage under high vibration, while a complete set of gaskets and sealing hardware keeps external contaminants at bay. This rugged build supports demanding driving habits and offers consistent performance for many seasons. The corrosion resistant properties of the treated steel ensure that the fuel reservoir stays sound even in harsh environments.
Complete Fuel Kit Simplifying EFI Installation
This all in one fuel system kit includes every component needed for a successful conversion, from the in tank module and sending unit to the filler neck, straps, vent filter and hardware. By matching factory fill and vent lines, it allows reuse of original plumbing and stock wiring plugs, cutting bench work and avoiding adapter fittings. Each part is designed for a precise fit, so installers spend less time sourcing parts and more time on calibration. This integrated approach leads to a faster swap and gives builders confidence that the system will perform reliably from first startup through high load driving. The plug in style arrangement ensures compatibility with the stock chassis design and wiring harness.
