The Trident Marine 365-0146 Type A1-15 Fuel Hose is a premium barrier-lined marine fuel hose designed for gasoline, ethanol-blended gasoline, and diesel fuel systems. With a 1/4 in. inside diameter, this hose is commonly used for smaller marine fuel runs, engine-mounted fuel connections, fuel system service work, and compatible inline fuel filter installations.
This is marine fuel hose, not a fuel filter. It is intended for fuel transfer and fuel delivery plumbing where the vessel layout, engine requirements, and applicable marine fuel hose standards call for 1/4 in. Type A1-15 hose.

Fuel System Compatibility
Common application context includes compatible marine fuel systems requiring 1/4 in. I.D. Type A1-15 fuel hose, including:
- Gasoline inboard fuel systems.
- Diesel marine fuel systems.
- Enclosed engine compartment fuel hose runs.
- Fuel line replacement during engine service.
- Small fuel delivery lines using 1/4 in. hose.
- Compatible inline fuel filters with 1/4 in. hose barb connections.
- Fuel system refits where low-permeation marine fuel hose is required.
Use this hose only where the engine manufacturer, vessel fuel system layout, and marine installation requirements call for 1/4 in. fuel hose.
Fitment Notice
Confirm the required hose inside diameter, fuel type, hose routing, fitting size, clamp style, bend radius, pressure requirement, and installation location before ordering. Marine fuel hose must match the fuel system and the space where it is installed, especially in enclosed engine compartments.
Do not substitute non-marine hose for fuel system use. Automotive or general-purpose hose may not meet the required marine fire, permeation, and fuel-resistance standards.
When This Hose Needs Replacement
Replace marine fuel hose if it is cracked, hardened, swollen, fuel-soaked, kinked, chafed, cut, leaking, or showing surface deterioration. Replacement is also recommended when fittings are changed, fuel tanks are serviced, an engine is repowered, or old hose no longer meets current fuel system requirements.
Fuel odor in the bilge or engine compartment should be investigated immediately, and any suspect hose should be replaced before returning the vessel to service.
Installation Notes
Route the hose away from sharp edges, exhaust heat, moving parts, and areas where it may be stepped on or crushed. Support the hose properly and avoid tight bends below the recommended bend radius. Use fuel-rated fittings sized for 1/4 in. I.D. hose.
Secure hose ends with approved marine fuel hose clamps or crimp-style fittings where required by the application. After installation, pressure-check the system as appropriate, inspect all connections for leaks, and recheck clamps after initial service.

Parts Desk Insight
The important detail on this product is that it is a fuel hose, not a filter. The 1/4 in. inside diameter must match the fittings and fuel system layout, while the Type A1-15 marine rating makes it suitable for demanding fuel hose applications where enclosed engine-space standards matter. Always replace aged clamps and inspect nearby fittings when replacing fuel hose.
