Viton tubing

[David Shriver]

I have read about many people using Viton tubing inside their fuel tanks. Why not run Viton for all the fuel tubing in a plane, not just the clunk line?

I'm finding with the ethanol gas my tygon doesn't stay flexible very long.

Because the only lines that really need to be flexible are the lines in the tank, plus with regular line from the tank to the carb you can see if it's getting fuel. And it's easy to replace if you really need to.

Yup what Kenny said. Also the viton is considerably more expensive than the tygon.

$$$$

I'm not really going to worry about $40 in fuel tubing on a $6k-$7k plane

I agree with that but Tygon works just fine outside of the tank. I think I bought either 5 or 10 ft of Viton 2 years ago and still have a bunch left as I use it for smoke connection to the muffler and for clunk lines. That 40 bucks per plane would add up to about 400-500 bucks for me if I were to use it every where in all my planes


I've also found that the fuel line that is sold at taildragger stays pretty flexible and I use that quite a bit as well outside of tanks and usually grab a few feet of it when I make an order from them.

What everyone said

Yup. What everyone else said. Viton for clunk line only. Even if money were no object, I don't want black fuel line running everywhere. I like to be able to see the fuel moving through the system.

Oh, and if you buy the real deal Tygon, like DuBro sells, it stays flexible for a long time. You can tell the real stuff if you look close at it. It will actually say Tygon on the line in small white print.

I agree!
