so I have a line right underneath the bubble my hand is on in photo 1. Photo two showz my hand on the loose line it blew I can't find the other ends connection point.. it is a long hard plastic hose that was just hanging out beside my tranny and rear seal........ no breaks and no uphill power any ideas? This end again runs into the firewall right under the big metal dimple my hand is on.

The hose in question goes into the firewall in between this bulge and the frame.

hand is on the line here.
