I hope to be able to use the pump in such a situation to be confident there are no leaks in the system prior to installing the R-134a.

Yup, that's what you're supposed to do. I think it needs to hold vacuum for around 30 minutes to prove that the system doesn't leak and also pumped out enough to eliminate all moisture. What do you use to evacuate (pump down the system) the refrigerant into? I know from the ac trade, some aren't too wild about contaminating their equipment pumping out a compromised system. Whatever gets pumped out can't be reused and has to be discarded, I assume to a recovery outfit. You'd think with a big leak you could hear it hissing when under pressure from inside or sucking air with a vacuum on it. Have you tried putting dye in? Unfortunately, you need a charged system to do that. I need to followup on my leak for dye.
That's quite the ability to ward off repairs by buying the tools for it. It does seem to have a fatal flaw of attracting other people's repairs, or is that just you?
Now, I can make you a onetime offer of something that will work for you AND your friends. I will give it to you for just a penny, but charge $20 for s/h. I got that idea from ebay. I have a very special, no an extraordinary repellant for keeping away elephants!!! To date, I have not had a single elephant come after me or even visit my house. It's great!!! I bet you are skeptical and would rather spend your money on another preventative tool. Fine. But, don't come running to me when you are stuck under an elephant!?!
