When the PO removed the canister and fuel vapor seperator, also removed the fuel line drop/pickup in the rear tank for gas to the Onan. Anyone got one I can buy?

Larry,
It is a part of the rear tank. Did he take it out and solder up the hole??
If there is no hole. Then maybe someone put an auxiliary tank in the rear.
Maybe they switched tank locations. If so, switch them back.
Or, you can drill a hole and put in a piece of 1/4 steel line and solder it in with an iron or a heat gun (not a torch).
Or you can do what Coachman did and T into the main fuel tank.

Matt,
On the far back drivers side corner of the rear tank is a pipe threaded hole on the top of the tank. It has a 3/8" (I think) pipe plug in it. I took the pipe plug out and find that it is open to the inside of the tank, so just assumed that this is where a pick-up for the Onan would go. What els could it be? Standard vent for the carbon canister is on the other side/middle of the tank.

It's a Coachman so there is no tap or fitting is there?

Yup, it's a coachman, and there is a tap, but only a pipe plug...no fitting.

Larry,
Mine is a welded in piece. Maybe transmodes when out differently.
Check and see if it has a draw tube down into the tank. If it does, get a street Ell and a 1/4 hose barb.
