BTW, I had one of those rubber caps split and blow off of a heater hose fitting. Made a big mess and left me stranded. Better to run a heater hose loop than use the caps.
Gotcha. I'll go buy extra ballast water and a ziplock bag full of rubber caps.
I'm not certain that the waterpump inlets are suction inlets, but according to internet sensation "starrman" they both are suction on the pump (
http://forums.corral.net/forums/94-95-tech/1297306-heater-tube-delete.html) Currently using the heater tube hole on the intake for a temp sensor (assuming that it should be getting the "hottest" water at that point in the system after the coolant has absorbed all the heat that it is going to). It makes sense that that side of the impeller would be suction (thermostat bypass pulling water through, and typically the one right under is the return from the heater core if I'm correct). With that said, I'll probably get everything set up in their correct locations, and then run the bottom tube from the new tank to the currently capped waterpump hole. I'll run the current radiator bleed to the upper hole on the tank. My only worry is that I still don't see how I can effectively burp the system this way unless I do what you said and run a "loop" from where my current temperature sensor is as well. That location should be the "highest" in the engine, and I assume that is where air wants to trap. Maybe it is best to run a bleed from the radiator AND tee it into a "bleed" from the current temp sensor spot (that intake hole near the intake), then send BOTH of them to the upper hole on that tank?
