Dave,
I didn't answer all your questions! The UAT remains full; it has a small air bubble at the top of the tank...and stays about the same size. No obvious leaks visible in the fuel tubing and fittings.

Keith,
On mine, the bubble at the top got to be 1/3 down. If it remains the same size, ie tiny, then it may be something else.
