I needed a oil gun for my old Wells Index 55. It has grease zerks on the ways to pump oil to them. So I picked up this mini grease gun from Auto Zone. I didnt need a big one.
All you need to to is cut the bottom off, throw the guts away and weld it back up solid. I did teflon tape All of the threads (fittings) to keep oil from pouring out of them. And, it has to be used upside down, so I bought the one with a flexible hose. To fill you just unscrew the body from the pump and fill.
