This listing is for 10 feet of original Tygon® F-4040-A fuel and lubricant tubing, proudly made in the USA and engineered specifically for 2-stroke outboards, including Mercury, Yamaha, and Suzuki performance marine engines.
 
This transparent fuel and oil bleed line is a high-quality replacement for the old, black OEM tubing that often becomes brittle, clogged, or cracked over time. With its clear construction, this line offers easy visual inspection, allowing users to instantly check for flow or detect blockages—an essential upgrade for external oiling systems on 2-stroke powerheads, where clear bleed lines help ensure reliable lubrication and prevent costly engine failures.
 
Tygon® F-4040-A is trusted across motorsports and marine industries for its superior material properties. It combines exceptional chemical resistance, flexibility, crush and kink resistance, and excellent transparency, making it ideal for use with high-octane race fuels, alcohol, nitro, 2-stroke oils, gear lubes, and standard pump gas.
 
It performs reliably in extreme environments, maintaining structural integrity across a broad temperature range. Its smooth interior surface minimizes fluid drag and sediment buildup, while its non-toxic, non-hemolytic, and biocompatible composition meets the highest safety and performance standards.
 
This 1/8" ID (1/4" OD) Tygon tubing is a direct replacement for various OEM bleed lines, including Mercury and Yamaha part numbers: 18-8048, 32-99130122, 99130122, 85606057, 85606064, 85606065, 883401, 8M0054152, 90445-07255-00, 90445-07M03-00, 90445-07M28-00, 90445-07M29-00, 90445-07MA3-00, and 90445-07MA6-00. Whether you're upgrading a race setup or refurbishing a high-output fishing outboard, this tubing delivers the clarity, resilience, and fuel resistance needed for peak engine performance.
 
Each package includes 10 feet of authentic Tygon® F-4040-A tubing, which is sufficient to replace all the bleed lines on a V6 Mercury Marine race powerhead. For standard fishing motors, 20 feet is typically required.
 
This upgrade ensures a cleaner, safer, and more dependable bleed system, making it a go-to choice for performance builders and marine technicians alike.
