Just a FYI.
With help from friends I was able to track down the fuel starvation problem.
It was not the fuel tank or the line or the carburetor.
It was a loose wire to the ammeter. Reconnect the wire with a nylon nut and now it seems to be back to normal. (What ever normal is).
So your T was starved for electricity!
I think Henry looked at electric vehicles but wasn't aware he made one!
Proving once again that 99% of fuel and carb problems are electrical in nature.
And vice versa.
Oh well, now your fuel system has been tuned to perfection!
