If you don't have a parts manual, look up the part number on the AGCO / MF parts site. Put the part number in the MF parts look up on Jack's Small Engines site. Their price is usually less than most other dealers. The price should be just over $500.

I would buy a gauge and check it myself before I bought a pump. Also, check your quick connectors.

Yes, you can install the mate to the QD, and activate the lever for that hose, and read the PRV pressure. If you have relief pressure, the pump is good.

Going along with what J_J said. When you hold the valve lever open, the pressure will build up until it gets to your maximum pressure. That will be when the bypass valve opens up and you can hear the engine load.

By the way, 700 psi can probably raise the loader empty all day. If you install a hyd gage in your system, you will be surprised at the pressure required as you are working with different loads. If you are lifting half a load, you may only see half pressure.
You only see max pressure when the loader might be working at the max load in lbs, or when you max out the cyl's.
