Type B1 Outboard Fuel Hose — 3/8" ID × 50 ft. | Gray | Part 305-0386
A 50-foot bulk roll of Type B1 rated outboard fuel hose in 3/8" inside diameter. Designed specifically for marine fuel systems, this hose meets USCG Type B1 requirements for use in outboard engine fuel delivery applications where the hose is not exposed to continuous fuel submersion.
The gray color and flexible construction make it easy to route through tight spaces in engine compartments, consoles, and under-deck fuel runs. Sold as a 50 ft. roll for custom-length installations.
Parts Desk Insights
Best Use Case: The standard choice for replacing or extending outboard fuel lines between the fuel tank and engine on boats where the hose runs through a ventilated space and is not submerged in fuel. The 3/8" ID is the most common diameter for outboard fuel systems on engines from 25 HP to 150+ HP. Type B1 hose is suitable for use with gasoline and gasoline/ethanol blends (E10). Cut to length as needed for custom runs. For inboard and sterndrive applications requiring Type A1 hose (fully submersible), see the Trident Type A1-15 Fuel Hose (365-0146). For smaller-diameter fuel hose, see the PVC Fiber-Reinforced Fuel Hose.
