In this regard, where can a fellow buy some soft tubing that works well in a clunk tank.
I have tried the Sullivan web site, but can't get info on softer tubing. Where else to find some sure would help.
I look for silicone tubing that's one size smaller in diameter than what I'd use externally. If there's a choice between thick wall and thin I go thin.
Remember that the stuff just needs to traverse the outside edge of the tank from top to bottom -- if the fuel isn't being thrown to someplace
on that outside wall, then something is wrong with the plane.
