Seachoice 365-0566 Low Permeation Type A1-15 Marine Fuel Line Hose 5/16" x 50 ft Black

The Seachoice 365-0566 is a premium low-permeation Type A1-15 marine fuel line hose engineered for enclosed engine compartment applications including fuel feed, return, vent, and transfer lines. Constructed with a dual-layer design, the hose features a nylon internal barrier liner that keeps fuel from making direct contact with the rubber, dramatically reducing permeation and eliminating diesel odor seepage.

Compatible with all common marine fuels, this hose handles gasoline (including ethanol blends up to E85), diesel, bio-diesel (up to B100), and alcohol-enhanced blends (CE-10). A polyester 2-spiral reinforcement provides excellent flexibility and bend radius without kinking, making routing through tight engine compartments straightforward. The NBR/PVC blend outer cover delivers strong resistance to fuel, heat, cold, UV, and ozone exposure.
