I recommend use of yellow Tygon Oil and Fuel line, instead of vinyl tubing, on your 2-cycle applications. It's a superior product and will stay flexible for years. You can obtain it from the following very nice people: http://www.pspmfg.com/FuelLine.html You will be glad you tried it and you will then tell all your friends about it--it's that good.

Yeah, this stuff is a lot better then the other stuff... I replaced the fuel line on my mowers with it, even though the old rubber lines were good. Very cheap as well, more flexible.
