Yes, just like other tubing, you have to get the correct tubing when it comes to Viton. There are a lot of different types.Jetpainter is correct I can testify first hand spring of last year I pranged I 50cc decathlon because of Viton tubing in the tank ran down the runway and as soon as pulled up the engine died and that was it the tubing had split of nipple in the tank so make sure you have the correct stuff.
