Trident Marine 5/16 in. x 50 ft. Barrier Lined B1-15 Fuel Hose - Gray

The Trident Marine 305-0566 is a 5/16 in. x 50 ft. boxed, barrier-lined fuel hose designed for outboard fuel systems. Engineered for durability, this hose features a fluoroplastic internal barrier that prevents direct contact between fuel and rubber, minimizing permeation and protecting the engine from ethanol-related degradation. The gray CPE rubber cover provides resistance to heat, cold, aging, and ozone, while the flexible construction allows for easy routing and reliable fitting retention.
