Trident Marine 5/16" x 50' Boxed Low Permeation Type A1-15 Fuel Line Hose - Black

The Trident Marine 5/16" x 50' Boxed Low Permeation Type A1-15 Fuel Line Hose in black is the professional standard for saltwater and freshwater vessel fuel systems. Built for anglers and boaters who demand reliability in their fuel delivery systems, this hose meets stringent marine certification requirements and handles the demanding conditions found on everything from center console fishing boats to offshore cruisers.

This fuel line hose features low permeation construction, which significantly reduces fuel vapor escape—a critical factor for fuel efficiency, emissions compliance, and fire safety in enclosed marine engine compartments. The 5/16-inch inner diameter accommodates standard marine fuel system fittings, while the 50-foot length provides flexibility in routing fuel lines through complex hull layouts and engine installations. Type A1-15 rating ensures compliance with USCG and ABYC standards, meaning it's engineered to resist ethanol-blended fuels, UV exposure, and the corrosive salt-air environment inherent to coastal boating.

The robust black cover protects the hose core from ozone degradation and mechanical wear. Serious anglers, commercial operators, and boat maintenance professionals rely on Trident Marine fuel line hose for both original installations and retrofit projects. This hose is an essential component for maintaining safe and efficient fuel systems in marine applications.
