Product Description: This innovative Tygon Low Permeation, CARB approved fuel line includes a new thermoplastic barrierthat helps protect the atmosphere from harmful hydrocarbons. This fuel line shows superior resistance to fuels and industrial lubricants while resistinghardening and swelling normally caused by hydrocarbon based fuels. This reduces the risk of cracking/leaking caused by "sour gas" which forms when unused gas isreturned to the fuel tank. Additionally, this line is specifically designed to withstand thedamaging effects of Ethanol. Temperature resistant up to 180
