Don't know why there are 2 pilot tubes. Unless (and you may have answered this with your observation) it was designed that way on purpose based on your observations of the pilot when the burner comes on. Draft pulls one pilot light away from thermocouple so their solution was to have another one that would take its place. Who knows because whoever engineered that thing is most likely dead so we can't ask him.

As long as your new pilot assembly gets the pilot close enough to the main burner to light it smoothly and the pilot light stays good looking and in the tip of the thermocouple the whole time, you only need the one. Probably cap the other one.

Disclaimer- I'm not there to see it myself so if you burn your house down, it's not my fault.

I still don't have a clear picture in my head of all the pilot tubing you have going on there. I see one that goes into a "T" fitting and yet another one that comes from some unknown location.

Hard to believe that, once upon a time, a gas valve had a manual bypass lever to allow gas to flow to the main burner. I've seen boilers with thermopile setups that had a manual switch (electrical switch, not manual lever) where you could keep the water up to set temp in a power outage even with no circulator pump operation. This would effectively turn the system into a gravity system while power is out. Still a shut off situation if the pilot were to go out because the thermopile wouldn't generate any power with no flame present. Are you saying you have a manual lever that physically allows gas to flow to the main burner? Just on-off; no way to regulate temperature?

Also, is this a furnace or a boiler? Assuming a hot water boiler based on other stuff you said.

Most of furnaces I've worked on the Thermocoupler was responsible to keep the pilot on. If the thermocouples isn't being heated by the pilot flame it doesn't sent the microvolts to the gas valve to maintain the patency of the gas to the pilot. The other thing I've found is that the tube to the pilot itself was obstructed. You could also have a bad gas valve.
