Frankly, I think you'd be better off just saving yourself some time 
and effort and running the pump output line directly to the pan. 
Forget about the damper and running thru that plate.

I think this comes up occasionally: The pressure side of the line 
goes along the left (driver's side in the US) side of the car, while 
the return is on the right.

The regulator is a shunt regulator, meaning that it dumps excess back 
to the tank to keep the pressure correct in the fuel loop around the 
engine. So the gas leaves the pump, goes back on the left, around the 
engine, bleeds off in front of # 1, and then returns on the right.

I think if someone did it backwards it just wouldn't run at all.
