Duane,
What are the two pins that stick out about an inch on each side?
I'm not sure, but I think one is for fueling, and one is for pressurizing. You can see that one line goes to the clunk, and one goes to the vent. I remember a bunch of people clustered around Tom once when he was flying the TBX. He had the fuselage open like the picture above, and was apparently having trouble with the pressurized tank. He was pumping a little bulb pump if I remember correctly. It was a long time ago.
Other ideas??
