the grey tool is a fuel line release tool but it's for the metal kind like what is used up on the intake the one that has the 2 metal clips going from a metal line to a braided line (I think)First pic I've seen of the whole shebang. I'm not even gonna begin to guess what that gray thing does. Unless it is split and opens to fit over the tubing, I don't see how it could be a release tool.
Oh well, Pawpaw is covered one way or another with his orders.
