IIRC, pressure is regulated on the return line so the one connected to the regulator is the return.  The FSM I have seems to back that up although it's a bit obscure.

I knew it!!! My argument was that being on the return it still regulates the pressure coming into the rail but on my buddies yj he traced it back to the pump and the supply went into the regulator..
I'm switching it back to return through regulator.
