lumbersawyer On your oil filter sounds like a nice neat job can't see why your grease gun hoses wont be fine,if to close to fit up make a circle. I learned to use heavy angle iron to screw the filter onto a nipple let it seal right on the steel then bend up brake tubing 1/4 inch to fit. Better to use flare rather than compression,they are harder to keep from seeping. Also use any size filter you like meter it to hold oil pressure up there.
