I am finally getting to the radiator plumbing and want to confirm what I'm about to do.  I have a single, custom radiator on the cool side of the engine.  I plan to run dash 16 lines from it to the inlet/outlet of the water pump.  "T'd" into one of these lines will be a what, dash 4,6(?), line from the bottom of the fill tank(1.5qts), which will also have a small line to an overflow tank.  does the fill tank "T" to the pump input or output line? for clarity, are we calling the output the top or bottom port?

it was mentioned that I may get by without a swirl pot, however, I will need a small (-4?) line for air bubbles tapped from the top of the water pump back to the fill tank, as well as a line from the high point of the radiator back to the fill tank, both of these entering the fill tank above the fluid level line.  am I missing anything?   can the water pump and radiator air bubble line "T" together before entering the fill tank?  is there an air bubble line needed off the rotor housings?  if I install a Schrader valve to pressurize the system, does it matter where? [ I suppose somewhere that doesn't involve removing the cowling].    kevin [gave up finding a plug for the oil pressure sender, must be 10mm x 1.25 threads? 10mm x 1 doesn't feel right, and just screwed it back in.]
