I just did this last week. Good question. I went to autozone and rented one. $20.00. When I returned it, got all my money back. It had a fitting that comes with it. I didn't use it though. I think they are all pretty standard. I didn't tell them what motor was being tested. If you can rent, borrow, or purchase one, it will will work. Good luck. Look at my thread: pulling motor. On pg 3. Somebody tells me what to do. Your thinking to much, I think most will work. Good luck!
