Trident Marine 3/8" x 50' Boxed Low Permeation Fuel Line - Black - Type A1-15 - 365-0386

The Trident Marine 3/8" x 50' Boxed Low Permeation Fuel Line – Type A1-15 (365-0386) is a premium, USCG-approved marine fuel hose engineered for safe, long-lasting performance in gasoline and diesel fuel systems. Designed to meet and exceed stringent marine safety standards, this barrier-lined fuel hose dramatically reduces fuel vapor permeation, helping control odors, protect onboard air quality, and comply with EPA/CARB emissions regulations.

Built for Marine Fuel System Safety

This Type A1-15 fuel hose is rated for enclosed engine compartments and critical fuel delivery lines, offering superior fire resistance and low permeation protection. The advanced barrier liner resists ethanol-blended fuels and modern gasoline additives that can degrade standard rubber hoses over time, making it an ideal upgrade for new installs and refits alike.

Durable, Flexible, and Easy to Install

Constructed with multi-layer reinforcement, this fuel line maintains flexibility for tight routing while resisting kinks, cracking, abrasion, heat, and vibration. The boxed 50-foot length is perfect for complete fuel system replacements on center consoles, cruisers, sportfishers, and yachts—saving time and money compared to buying shorter lengths.

Wide Fuel Compatibility

Engineered for today’s fuels, this low permeation hose is compatible with:

  • Gasoline and ethanol blends up to E85

  • Diesel fuel

  • Biodiesel blends up to B100

Ideal Applications

  • Fuel feed and return lines

  • Vent and transfer lines

  • Inboard and outboard fuel systems

  • New installations and fuel hose replacements


Key Performance Standards

The 365 series is built to comply with the most demanding marine regulations:

  • Type A1-15: Rated for 15 minutes of fire resistance in an open flame test.

  • Low Permeation: Exceeds EPA and CARB requirements ($15\text{g}/m^2/24\text{hr}$), meaning it significantly reduces "gas smell" in bilge areas and fuel evaporation.

  • SAE J1527 & ISO 7840: Fully compliant with international standards for marine fuel hoses.

Construction Features

  • Inner Tube: Specially formulated synthetic rubber that is highly resistant to alcohol (ethanol) and diesel fuels, preventing the "flaking" that clogs carburetors and injectors.

  • Reinforcement: High-strength synthetic textile plies provide excellent kink resistance and high burst pressure ratings.

  • Outer Cover: Ozone and UV-resistant rubber prevents cracking and "dry-rot" even in high-heat engine room environments.


Installation Safety Tip

Double Clamp for Safety: For fuel fill and supply lines below the waterline or in enclosed spaces, the USCG recommends using two 316 stainless steel worm-gear clamps at every connection point to ensure a vibration-proof, leak-free seal.
