I'm in the process of replacing all the metal lines and rubber hoses. Got everything unhooked, but I haven't been able to get the rear rubber hose out of the brackets. They're not frozen, since they turn with a wrench. I can't find a clip holding them, and I haven't been able to pull or tap them out. It looks like a P.O. sprayed some kind of sealant gunk all over there, so maybe there's a clip that's buried? Or maybe it's just gunked and needs a good hit with a hammer? I didn't want to do that until I asked someone who's replaced these before (obviously this is my first time).
