How do you remove stock fuel disconnect at tank?
So I finally got around to inspecting my GT because of an occasional fuel smell and fully expected to find a leak or seepage at the quick disconnect boss, but once apart I cannot see any sign of any kind of leak (ran it up to operating temperature on the centerstand), nor can I see any telltale signs of leakage (stains, etc.) I guess I was being over-sensitive(?) I think I do see a hairline crack in the mounting boss (don't have the tank completely out yet) but as I said, no sign of any leakage.
From what I read if there's no current leak the BMW official fix is to simply install a metal reinforcing ring rather than replace the entire pump so since I already have one of these I'll go ahead and install it rather than bother with taking it to the dealer, doesn't sound like they will do any more than I can anyway.
Anyway, my question... how do you release the stock quick disconnect? I see what looks like a small metal retaining ring with a little knob on it, do I pry that out, or..? I don't see what else I could do...
Also when the line is removed will fuel come pouring out of the tank (if it is not emptied first)?
