Trident Marine Fuel Hose - Bulk

Trident Marine Bulk Fuel Hose: Purpose-Built for the Marine Environment

When it comes to marine fuel systems, the hose you choose is a critical safety component — not just a connector. Trident Marine, the oldest North American marine hose company, has built its reputation on engineering hoses that meet the unforgiving demands of saltwater environments, fluctuating temperatures, and today's ethanol-blended fuels. Their bulk fuel hose offerings represent the pinnacle of that expertise.

The Series 365: Trident's Flagship Bulk Fuel Hose

Trident's most widely recognized bulk fuel hose product is the Series 365 Barrier-Lined Type A1 Marine Fuel Hose. It is a premium marine fuel line designed for gasoline, diesel, and their ethanol or bio-diesel blends, featuring a unique internal barrier liner, dual spiral reinforcement, and advanced fuel, fire, and age-resistant materials that deliver exceptional durability, low permeation, and reliable performance even in tight installations.

The 365 Series hose features a unique "Barrier Liner" on the inside surface of the tube, so fuel is never in direct contact with the rubber itself — a design that dramatically reduces permeation and extends service life. It is rated for both gasoline (including ethanol blends up to 85%) and diesel (including bio-diesel blends up to B100).

Certifications That Matter on the Water

Buying bulk fuel hose for a marine application means compliance is non-negotiable. The Series 365 exceeds ABYC H-24 & H-33, SAE J1527, ISO 7840, and USCG Type A1-15 standards, and is CARB Executive Order RM-17-008 and EPA certified for low permeation to the Type A1-10 standard. This matters because the EPA has lowered the acceptable fuel permeation rate for gasoline fuel supply and return lines, and Trident's Series 365 continues to meet and exceed these new specifications.

Why Bulk Hose Format Matters

Purchasing fuel hose in bulk reel format gives boat builders, repair yards, and serious DIY boaters the flexibility to cut precise lengths for any installation — from distribution and return lines to vent and transfer applications. Founded in 1985, Trident Marine has focused on producing hoses that excel in durability, performance, and reliability, and their fuel hose is engineered to meet strict industry standards, providing superior resistance to harsh marine conditions, fuel degradation, and temperature extremes.

Trident was founded with an intense focus on marine hose quality, performance, durability, reliability, standard conformance, and consistency — in the interest of long-term safety for boaters. That ethos is evident in every foot of bulk hose they produce.
