1978-1987 Oldsmobile Cutlass LS EFI Fuel Tank Kit
Tackling an LS swap in a 1978-1987 Oldsmobile Cutlass four door demands precise fuel delivery under varied load conditions. This EFI fuel tank kit delivers a 255 LPH Walbro pump and a fully assembled module that seats directly in the OEM tank cavity using factory mounting points for a clean install. Installation hardware and a molded filler neck pair with original sensors to maintain accurate level readings without custom brackets. American made gaskets and stainless steel straps resist corrosion and vibration while the system can accept an optional 400 LPH pump for builds pushing beyond 550 hp.
Complete Module Assembly for OEM Fitment
This fuel module arrives fully assembled, allowing it to seat directly in the original tank cavity of the Cutlass without custom brackets or fuel cell modifications. By matching factory mounting points and using the stock filler neck position, the kit preserves the vehicle's underbody layout and reduces installation time. The pre-configured sending unit integrates with the factory gauge and wiring harness to maintain accurate level readings. From the vent filter to the gaskets, every component snaps into place for a clean, professional fit.
Brushless Pump Architecture for Smooth Fuel Delivery
At its heart, the 255 LPH Walbro pump features a brushless motor that minimizes internal friction and heat buildup, extending service intervals and reliability. This design sustains a consistent flow rate under heavy acceleration and sustained high rpm, guarding against fuel starvation in builds up to 550 hp. Reduced vibration and noise result from precision balancing, while the sealed housing resists contamination. The outcome is a steady supply of fuel that keeps throttle response immediate across the rpm band.
Modular Upgrade Path for Higher Power Builds
The kit's design accommodates an optional 400 LPH pump without any changes to the mounting assembly or wiring layout. Swap over in minutes by replacing the internal pump cartridge, giving you the capacity needed for extreme horsepower applications. This forward-thinking approach lets you start with a proven 255 LPH setup and scale up as engine upgrades demand more flow. No special tools or secondary brackets are required, ensuring your project stays on schedule.
Corrosion Resistant Construction for Long Service Life
Every strap, gasket, and hardware piece is crafted from premium stainless steel and engineered polymers, providing robust resistance to moisture, road salt, and vibration. American made materials undergo strict quality checks and traceability protocols, ensuring each fuel system meets exacting standards. The molded filler neck and precision-cut gaskets create a leak-proof seal that endures thermal cycling and daily use. This rugged build quality delivers confidence whether you're commuting or competing on the strip.
Engineered for a precise fit and reliable fuel delivery throughout your LS swap project.
