I have a fuel line question. Since it is starting to warm a bit here, I thought I’d do a bit of PM on my SU. One of the things I read lately was a recommendation to replace the fuel lines every year because even the tyvek hardens with age and exposure to gas. I don’t think most of mine are that hard after one season, but I took the tank apart and the clunk line is as stiff as a board. I could hardly cut if off the clunk and brass tubing!

So a question … I have new tyvek line, but with a short length like is in the tank, even new line is not very flexible. What are people doing about that? It really needs a much heavier clunk to be effective and drop to the bottom when inverted, but I have never seen heavy clunks. So what is the solution?
