Here I am again bothering you all about my fairey. I can't figure out how to get gear oil into it. It's the version on the split transfer case. The filler plug is located directly behind a gear that is spaced only 1/8" behind the filler hole. Not enough room to get a hose or nozzle in there. I'm thinking about getting some fittings to screw a filler hose into the plug hole. Problem with that though, I couldn't tell when it was full. There is probably something obvious I haven't considered. Any ideas? Thanks.
