never seen that happen. I almost never burn off the unused fuel,
though. If I'm going to be putting one up for more than a couple of weeks,
I'll run it dry and add after-run, but I fly my main two every couple of
days.</FONT></SPAN></DIV>

using? All of mine are using Hayes tanks, and that doesn't look like what
you have.</FONT></SPAN></DIV>

color=#0000ff size=2>The other thing is that I'd expect the check valve to allow
air to come into the tank as the fuel was being sucked out. Unless I'm
mistaken, the check valve keeps air/fuel from going out of the tank but not
in. Perhaps there's a problem with your check valve?</FONT></SPAN></DIV>
