RE: Fuel clunk line for gas?
Check out the fuel line made by Echo for their power equipment. Stands up very well to todays gas and is very flexible. It's also available in several sizes. I work on small engines for a living, and find the line from Echo to need less replacement than other brands I work on. Just ask you local dealer to show you the "bulk" Echo fuel line. I beleive what you need would be #90014 or #90015. I don't use gas anymore so I have sorta gotten away from the set-ups.
