1978-1987 Cutlass LS EFI Fuel Tank Rated 255 LPH

Known for precise fit and consistent flow, the 255 LPH Walbro pump supports LS engines up to 550 hp and installs in 1978 1987 Cutlass four door EFI conversions. Crafted in the USA from premium materials and backed by rigorous quality checks, this tank kit delivers reliable fuel supply and lets you upgrade to a 400 LPH unit. Every assembly includes exact fit components and prewired connections for a straightforward installation that stands up to daily driving and spirited runs.

1978-1987 Oldsmobile Cutlass 4-Door EFI LS Fuel Tank Kit with 255 LPH Pump

When installing an LS powerplant in a 1978 to 1987 Oldsmobile Cutlass four door chassis, ensuring steady fuel supply under heavy throttle is critical and this EFI Fuel Tank Kit delivers by seating the entire assembly directly into the stock tank cavity complete with a 255 LPH Pump for consistent pressure. Installation relies on factory mounting points and the original filler neck to simplify fitting and maintain sensor readings without carving custom brackets or altering the underbody layout. American made gaskets and stainless steel straps guard against corrosion and vibration, while the design also accepts an optional 400 LPH unit should your build demand higher output, keeping fuel flow steady across the rpm range and preserving throttle response throughout extended runs.

Advanced Brushless Pump Technology

The heart of this EFI tank kit is a 255 LPH pump featuring a brushless motor design that cuts internal friction and heat buildup. By eliminating brushes, the unit achieves smoother operation, reduced maintenance intervals, and enhanced durability under sustained load. Precision balancing of the rotor assembly suppresses vibration and noise, ensuring that fuel delivery remains consistent even during hard acceleration or extended high rpm use. The sealed housing guards against dirt and moisture intrusion, preserving pump efficiency over thousands of miles. This engineering focus translates directly to stable fuel pressure, so throttle response stays immediate from idle through redline.

Seamless OEM Tank Fitment

This fuel tank kit installs directly into the original tank cavity of a 1978 to 1987 Cutlass four door without any custom brackets or body modifications. Every component aligns with factory mounting points and uses the stock filler neck position, preserving the under body layout and simplifying the install process. The preassembled sending unit plugs into the factory wiring harness and retains the original level sensor, which means accurate gauge readings without the need for adapters. American made gaskets and stainless steel straps secure the module against vibration and road shock while preventing fuel leaks. By matching the vehicle's original design intent, this kit reduces installation time and helps maintain a professional fit and finish.

Scalable Fuel Flow for Future Power Upgrades

Engine builders who push beyond standard power targets will appreciate the kit's modular upgrade path. Without altering the mounting assembly or rewiring, you can swap the internal pump cartridge for an optional 400 LPH unit in minutes. This plug-and-play approach lets you start with a proven 255 LPH setup and later increase capacity as boost or cam upgrades drive higher fuel demand. There is no need for additional tools, secondary brackets, or custom plumbing, so your swap project stays on schedule. Whether you plan for a mild street cruiser or a more radical performance build, this system scales with your LS engine's evolving requirements.

Durable American Made Material Construction

Every gasket, strap, and mounting bracket in this kit is manufactured in the USA from corrosion resistant materials that withstand road salt, moisture, and vibration. Stainless steel straps deliver high tensile strength without the risk of rust, while precision molded polymers form a leak-proof seal against the tank flange. Each vent filter and hardware component undergoes strict quality checks and traceability protocols to meet rigorous standards. The result is a fuel delivery system that endures daily driving as well as track sessions, giving builders confidence in both reliability and longevity. This robust construction ensures your LS swap operates smoothly for years to come.

This kit delivers dependable fuel flow and a seamless fit for your LS swap.
