Trident Marine 5/8” A2 Fuel & Vent Line Hose - Black - Sold by the Foot

The Trident Marine 5/8" A2 Fuel & Vent Line Hose in black is purpose-built for anglers and boaters who demand reliability where it matters most—fuel system integrity. Whether you're running a gasoline engine with ethanol-blended fuel or a diesel setup with biodiesel, this marine-grade hose handles both with proven dependability. Sold by the foot, it gives you the flexibility to cut and install exactly the length you need for fuel lines, vent lines, or overflow applications without excess waste or compromise.

Constructed to A2 specification standards, this 5/8" inner diameter hose is engineered to resist the corrosive effects of modern fuel blends, including ethanol and biodiesel additives that degrade inferior hoses over time. The black rubber construction provides UV resistance and flexibility in cold water environments, critical for boats stored or operated in variable climates. Trident Marine's formulation ensures the hose maintains its structural integrity under pressure cycles and temperature fluctuations typical of engine operation, reducing the risk of fuel leaks, vapor escape, or system failures during long days on the water.

This hose is ideal for replacing worn fuel or vent lines on inboard engines, outboards, and auxiliary power systems. Installation is straightforward with standard marine hose clamps, and the 5/8" diameter accommodates most contemporary marine engine fuel systems without adapter fittings. Order the exact footage your application requires—whether patching a single failed section or rebuilding an entire fuel system—and have the peace of mind that comes with OEM-specification marine hose backing your vessel's performance and safety.
