Thanks again JJ. I could barely make out the printing - it's sorta worn off since I'm down to the last 15 feet from a 50 foot roll, but it says 4040, so I guess I'm good to go. I only run non ethanol fuel and have had no problems with the tygon, but hoped I had not sold a saw to someone with problematic fuel line. I like the tygon over the black line because you can see the fuel flow thru it.
