Okay, its sounds like neoprene and tygon are only good for 1 season. Has anybody actually used viton for a long enough time period to know what the expected life should be in our application? I'm happy to pay more, if it would last for 4 or 5 years.
If you keep some fuel in your tank the tygon will stay soft and last years. Next time I re-plumb my tanks (next winter), they get the Viton. I have 3 feet of it sitting in my shop.
As far as neoprene goes, I won't ever use it again....not even for one season. Gummed up my carb screens really bad.
