I have been using "Oregon" fuel line for a couple of years with no problems. I have heard a lot about "Tygon" fuel line. Yesterday I had a customer who needed the fuel lines on his trimmer replaced. He said he did not want me doing it because I was not using "Tygon" fuel line. Is Tygon a better product? it is a little more expensive. Is it worth the extra money? All comments will be greatly appreciated.
