The 3/8" I.D. Fuel Line Assembly Kit includes an alcohol-resistant primer bulb, a 7' fuel line hose, and a thermoplastic barrier that helps protect the atmosphere from harmful hydrocarbons escaping through the carcass of ordinary fuel hoses. It surpasses all of CARB's stringent permeation requirements, features an abrasion and weather-resistant cover to protect against external application abuse, and is approved for use with bio-diesel fuels.
