Trident Marine 3/8" x 50' Boxed Barrier Lined B1-15 EPA Compliant Outboard Fuel Line Hose - Gray

The Trident Marine 3/8" x 50' Boxed Barrier Lined B1-15 EPA Compliant Outboard Fuel Line Hose in gray is engineered for serious boaters who demand reliability and safety from their fuel systems. After years on the water, any seasoned angler knows that fuel line integrity directly impacts engine performance and vessel safety. This 50-foot hose delivers the EPA compliance and construction quality needed for modern outboard motors, whether you're replacing worn fuel lines or building a complete fuel system for a new-to-you boat.

What sets this fuel line apart is its innovative barrier-lined construction—a specialized interior liner that prevents fuel from making direct contact with the rubber tube material itself. This design significantly extends hose lifespan by reducing ethanol-related deterioration and age-related degradation that plague traditional fuel hoses. The B1-15 rating ensures the hose meets SAE (Society of Automotive Engineers) and EPA standards for outboard fuel systems, meaning it's formulated to resist fuel permeation, ozone, and temperature fluctuations. The 3/8-inch diameter accommodates most standard outboard fuel delivery systems, and the full 50-foot length in a single boxed unit eliminates mid-line connections that can become weak points during extended trips.

Boaters replacing fuel lines on outboard engines—from small portable motors to larger inboard-outboards—benefit most from this Trident Marine hose's proven durability and regulatory compliance. Installation is straightforward with standard fuel line clamps and fittings, and the gray color resists UV fade better than clear alternatives when routed along the gunwale or transom. Before purchase, verify your specific outboard's fuel line diameter and length requirements; this 3/8-inch specification is common across most recreational and commercial outboard platforms, making it the right choice for typical mid-range outboard applications.
