DIR SPG/Console?

[beeger]

Jason - is your question how to keep the knot from coming undone, or is it how to keep the knot from sliding up and down the hose? If the former, the trick is to melt the ends of the line down a bit and mash the ends flat so the ends won't pull through the knot, as DRE indicated below. If the later, that's why I don't like the specific knot on the website for things like the long hose (I'm also not crazy about it for the backup lights or SPG, although it does work better for these). There are other ways to tie the line here.
