It goes on the ramp where the cut out is for the diverter.

I'm not sure which is the correct side up for that part on the JP I have

I couldn't find any new from factory pictures

Maybe I it shows in the manual?

When I put mine back together after shopping it, I put it on upside down, which I realized after looking at my teardown pictures. So, at least to me, it goes on opposite of what you might think. Unfortunately, I am on vacation and cannot look at my JP nor do I have access to my tear down photos. However, from memory I believe the bends go down. If you zoom in on this photo that I posted in the JP mods thread, I think you can just make out that the bends go down.

I'll have to check mine. There was some good reason I did it one way over the other... I think I had trouble with it fitting/screwing it on one way

OK, mine is an outtie
