Sorry it took so long to reply . Went to town yesterday and stopped at my favorite parts store. They had a air operated grease gun for under $30. Looked good so I brought it home. uses the large grease cart. Loaded it up today and greased a old outboard. worked well, had enough pressure to push the old grease out. Think on the air comp I am going to find a small generator to drive my pancake compressor and see if that will blow up the tire. LG
