5/16" x 50' Boxed Barrier Lined B1-15 EPA Compliant Outboard Fuel Line Hose - Gray
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 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.
