the ? on your drawing is an 'in' from an overflow on one or both of your heat exchangers. Your system will self-bleed this way. I think CED has a good diagram on how to set this up. At least they used to, let me see if I can find it for you.
Here it is: http://www.crateenginedepot.com/store/pdfs/sidekit.pdf
Read the section under option B - about the air bleed fitting. Make sure you put in the .040 orifice mentioned in the doc.

Well then just run it to your stock heat exchanger just as described in that document. All it is meant to do is bleed the air from the system. You should notice a slow flow of coolant flowing into your opt. B tank once it's bled.

There is no "out" on the option B... there is just 1 hole...
the nipple on the top is for over flow.. and should connect to the top (or bottom, pretty sure top) of the stock heat exchanger.

If my bleed orifice is in my stock heat exchanger can I still run my cobra heat exchanger or do I need to tap into the cobra to bleed to that h/e also?

that first diagram looks correct. but I get confused sometimes because people will make the two outer laminovas the in ones and the center ones out compared to the diagram you have there where the coolant goes in the middle then out the outer two... dunno what is better

Ok well looking at the latest imagine in my last post how the hell does coolant get back up the the surge tank? does coolant from the overflow on the stock heat exchanger fill it? or does coolant just circulate back and forth in the single 3/4 hose going from the T to the surge tank?

Good if anyone thinks I should add notes to the diagram anywhere let me know and I will keep updating it. I think this will really help people understand Option B/Dual Pass/Extra H/E.
