While my pump is separate from the vacuum tank, I would still recommend the following. I would remove the pump and completely rebuild it. The rebuild is much easier than it sounds. It basically consists of replacing the diaphragm, 2 orings, in your case the motor, and the 4 one way valves. Having done it twice, I would estimate I could do it from removal to reinstallation in less than 2 hours. First time might take you 3 hours. Fully rebuilt, the pump should function for many years with only changing valves every few years.

I'm tired of fast moves, I've got a slow groove, on my mind.....
I want to spend some time, Not come and go in a heated rush.....
