the dealer here orders in the tygon and it's strange. the label on the box says oregon but the line itself says tygon on it in white letters. i have suspicions that it is all the same **** besides that yellow ebay garbage. i've tried every yellow line available, even that blue line. i judged fuel lines long before i joined AS. i only use line that is similar to OEM as that is all that seems to last and not turn into a goo. in the past i used to install a new line in any saw and always used tygon. i soon began to realize that the tygon was literally melting in layers it seemed. if you let the saw sit anymore then a couple weeks the thing wouldn't start because the melted layer on the inside plugged the line. it's not an issue on saws that get used everyday as it keeps the line clear but it will still get gooey. if you've had a saw that has had tygon for any length of time pull the line and just look at what the part that was inside the tank looks like. it stiff'ns up and has a gooey coating. all in all, the fact tygon can't be bothered to make something that actually fits is annoying enough, the fact that the line is trash is just an added annoyance. my findings are that any transparent/shiny line is gonna be junk (so far for me it has been anyways). of course, guys can use what they want. just trying to help with my findings and i haven't just replaced a few lines in my life like most here LOL
