Mike, where does the hose go that is coming out of the top of the welded on neck?
I am trying to work out the best option for my set up, but the steam pipe is confusing me.
My radiator filler is about 20mm lower than the upper hose on the water pump, but the steam pipe is then higher again.
Original plan was to install one of these inline fillers
Moroso Radiator Hose Fillers 63745 - SummitRacing.com near the upper hose on water pump to allow it to fill without air getting trapped (or would it still be trapped in heads?). I was then going to just run the overflow to a recovery tank. Only problem is the steam pipe would be higher. Do you think it would work to just tap the steam pipe into the inline filler? Not sure if the air/steam would push through into the system or get stuck at the top of the pipe.
