3/8" Barrier Lined B1-15 EPA Compliant Outboard Fuel Line Hose - Gray - Sold by the Foot This hose is built with the best fuel and age-resistant formulations and a unique "Barrier Liner" on the inside surface of the tube, so the fuel is not in direct contact with rubber. This greatly reduces fuel permeation and prevents ethanol degradation of the rubber tube, which can cause small pieces of rubber to reach and damage the engine. That is particularly important considering the prospect of higher ethanol blends (E-15) available at gas stations next year.  Features:  Sold by the Foot Provides extraordinary resistance to fuel permeation, aging, heat, cold, and ozone   Also, provides excellent rope-like bend-ability and fitting retention For both gasoline (including ethanol blends up to E85) and diesel (including bio diesel blends up to 100%) EPA Certified and CARB Executive Order for low permeation Type B1-15 NMMA Type Accepted & CE certified Applications: Marine Fuel Hose for distribution, return, vent and transfer For all marine fuels including gasoline, alcohol blends (CE-10), diesel and bio-diesel Construction: Tube: Fluoroplastic Internal Barrier Cover: Gray CPE Rubber Reinforcement: 2-Spiral Polyester Plies  Temperature Range: -20°F to 212°F (-28ºC to 100ºC) Specifications: Inner Diameter: (inch) 3/8" / (mm) 9.50 Outer Diameter: (inch) 0.588 / (mm) 14.9 Burst Pressure: (psi) 175 / (mpa) 1.21 Working Pressure: (psi) 35 / (mpa) 0.24 Bend Radius: (inch) 4" / (mm) 101.6 Weight: (lb/100 ft.) 10.5 / (kg/m) 0.156 Permeation Rate (Standard is (15g/m^2/24hrs (CE10)): 5.0 *The #305 series exceeds ABYC H-24, SAE J1527, ISO 8469 B1, USCG Type B1-15
