LS engine EFI Fuel Tank Kit with 255 LPH Pump for 1978-1987 Oldsmobile Cutlass
Swapping an LS powerplant into a 1978 to 1987 Oldsmobile Cutlass four door demands a reliable fuel supply under sustained load and this EFI tank kit meets that need by fitting directly into the stock cavity and delivering consistent pressure with a 255 LPH pump. The assembly uses factory mounting points and retains the original filler neck to maintain accurate sensor readings and avoid underbody modifications. American made gaskets and stainless steel straps guard against corrosion and vibration while a plug and play cartridge system lets you swap in a 400 LPH unit for increased output without new brackets.
Brushless 255 LPH Pump Optimized for LS Engine Swaps
The core of this fuel tank kit is a 255 LPH Walbro pump featuring a brushless motor that minimizes internal wear and heat generation. By eliminating brushes, the assembly achieves smoother operation and reduces maintenance intervals, making it ideal for sustained throttle applications on LS engines. Precision balancing of the rotor and sealed housing design guard against vibration and moisture intrusion, ensuring consistent pressure even under heavy load. With support for up to 550 hp, this pump maintains stable fuel flow from idle through redline to preserve throttle response and engine health.
Plug and Play Upgrade Path to 400 LPH Capacity
This kit incorporates a modular cartridge system that lets builders swap the installed pump for an optional 400 LPH unit in minutes. Without altering the mounting bracket or rewiring the harness, you can boost fuel flow to meet the demands of forced induction or high lift cams. The quick-change design requires no special tools and eliminates custom plumbing, letting you stage your build from a reliable base to extreme output with minimal downtime. This future-proof approach keeps your swap on schedule as power targets evolve.
Direct OEM Cavity Integration for Simplified Fitment
Designed specifically for 1978–1987 Oldsmobile Cutlass four-door models, the entire assembly drops into the stock tank cavity and secures to factory mounting points. Retaining the original filler neck preserves underbody clearance and ensures accurate readings from the level sensor. The preinstalled sending unit plugs directly into the vehicle's wiring harness, eliminating the need for adapters or custom harness extensions. By matching the factory layout, this kit reduces installation time and delivers a seamless professional fit.
Corrosion Resistant USA Components for Long Service Life
Every gasket and strap in this assembly is made in the USA from premium materials chosen for strength and chemical resistance. Stainless steel straps resist rust and maintain clamping force under vibration, while molded polymer seals create a leak-proof barrier against fuel and environmental contaminants. Hardware and filters undergo strict quality inspections to ensure traceability and reliability. This robust construction stands up to road salt, moisture, and thermal cycling, protecting your investment whether you log highway miles or hit the track.
Engineered to OEM standards with premium US-made components this kit ensures reliable fuel delivery for your LS swap.
