We run the lubricated Gast 1550 pumps and use Tractor Supply Brand vacuum oil so I'm sure that would work in yours as well. Many of the producers that use the old farm pumps use that too. Our 1550s use minimal amounts of oil. A gallon will last a few years. We have three of the pumps and one has the same oiler as in the link below and the other two are a little different style. We took all of our pumps apart to clean and inspect like you did and all three pull 26" plus. Had to hone one to clean it up but as long as things are smooth and the vanes are not chipped or worn excessively you should be good to go. We are able to get bearings for the 1550 at our local Kaman Bearing store. Not sure about the 2065 though. I would assume you can. There is a wick in these oilers so be sure that is in good shape also. It looks like a pipe cleaner and I believe some have used pipe cleaners as replacements. http://gastmfg.com/products/compress...ate-drive/2065
