Viton clunk line

Viton really is the way to go for the clunk line inside the tank. This is after 3 years, and you can see it is still flexible, like new. The yellow Tygon external lines get replaced every Winter because they are stiff.

Using tygon in my tanks, viton on the outside and ethanol free gas for three years now and not one single problem (knock on wood)

I switched over to viton clunk lines last year and no problems...also use it for smoke connection on muffler too...seems to last alot longer on the hot smoke nipples than neoprene.

Also have guys in our club who have had the same clunk lines for the last 3-4 years using viton with our crappy ethanol gas with no issues.

Definately Viton on the clunks, tygon on the inside is asking for a stiff clunk line and flame out.
