Hey Bruce, I am glad you got the manual, I found it quite helpful, as Steve and Ed mentioned their pumps, as well as the one on my 03 Marquis, are located up under the entry steps, and as We all have different models and years , I can't imagine them changing the location on your Patriot ( but hey it's a motorhome, crazier things have happened)
You do have to get right under there to see it, if you do a search for Ids levelling, you should find a thread of mine with some photos of the pump and specs on the motor, as I had to change it last year.
