I always use the male and female garden hose coupling in the main water line from the pump so I can quickly disconnect the hose and run the motor with a garden hose.

Please make sure to start the engine before opening the water valve and turn the water off before shutting down the engine...You do not need to open the water all the way, just enough to get some flow through the engine...Hydraulicing can occur very easily so be careful...

I have a line coming out of my jet pump, then it has a ball shutoff valve, then a T-fitting and then it goes to the motor.  I hook hose to this??  So then where do I run water to for the jet so I don't mess it up?  Or is that done using that same line?

I always pull the driveline to run the motor so not needed on mine, I am not sure of the importance of the water going to the pump if your only going to run it for a short time (2-3 min.) but longer I would get some water in there to keep things wet, Tom will chime in here I'm sure but I dont think its a big deal to be honest, especially if the pump is stock and has factory clearances, mine is too tight to run dry at all.
