Injector pump head port sequence

Does anyone know of where there is a diagram showing the sequence of ports (as far as which cylinder goes to which port) for a Bosch PSB-6A-80C diesel injector pump.
 
Should be pretty much self expanetory.Each prebent line will only go to one cylinder.Think of it as a puzzle of sorts.
 
I'm aware of that fact. It's when the lines don't exactly match the the ports in the head, if you see what I mean. I've checked the Bosch manual (on-line) and it doesn't show where the ports in the head go to which cylinder.
 
If you can find any of the lines that make it clear which port it fits, and know which direction the pump rotates, the firing order is 1-5-3-6-2-4. It's a matter of the process of elimination, sort of.
