I also have had a fuel transfer sight gauge of polyuethane in service for
about 600 hours with no (or very little) discoloration and/or clouding. In
the beginning, I didn't completely trust the thing but have experienced no
problems to date. One thing I did a little bit different because of my
original mistrust, was to make the tubing visible after going thru the tank
selector valve. This way, I only have one transfer sight gauge, but it's
obvious when you see bubbles which wing is empty from the position of the
valve.

Incidentally, the header sight gauge is not polyurethane (don't remember
just what I used) but it has gotten very hard and slightly cloudy. Although
it has not leaked or given any other troubles, I plan to exchange it for the
polyurethane at next annual.
