Bulent,
I have that same purge tank on my 20B installation.  Here's how I have it 
plummed.  The bottom fitting on purge tank T's into the inlet (lower) side 
of the water pump (the 20B pump has a fitting that I used).  The side 
fitting goes to the top of the outlet side of the radiator (I had to weld a 
-6 AN fitting to accomplish this).  I did not use the fitting on the rear 
side housing, but instead just put a fitting on the top of the water pump 
so I can open it while filling the engine with coolant and it will allow 
the trapped air to escape.  You could remove the upper rad hose to 
accomplish the same thing.  I figured the small bubbles will get trapped in 
the outlet tank on the radiator and get sucked into the purge tank.

One last thing.  I installed a coolant level sensor in the purge tank to 
let me know of low coolant levels.  So far I have 3 hours run time on the 
system and it appears to be working as intended.

Sorry, no photos. (I'm at work at this time).
