Hehehe yes between the carbs and air box. It just looked like the smoothest route to keep from kinking the hose and the large clear filter just lays on the boots so no weight pulling on the hose and fittings that way. I put the filter close to the #4 carb so I can see it easy if I squat down but can't really see it if standing up. Sounds worse than it looks. :silly: :blink: :laugh:

Clear (or colored) vinyl will go bad in a matter of days or weeks. Clear (or colored) urethane tubing may last a year, but will eventually harden, crack, turn brown etc. In Illinois we get a lot of alcohol in the gasoline and it kills plastic fuel line very quickly.
For anything permanent you really should only be using black rubber (Viton or maybe nitrile) fuel line... thin-wall if you can find it. My 550 uses 5/16", but I have to use clamps to prevent leaks.
