Does anyone have a line on where to get the breather hose tubing that WDK uses? I'm currently using pool vacuum hose tubing that is 1/4-1/2" less in diameter than what I need. I cut a 1" section and split it down one side to wrap around the breather tubing to take up the extra volume but it is not a clean look and the silicone is already seperating from the I siliconed the hell out of it but the seal is not as good as I'd like. I've searched both Lowe's and Home Depot.
