Gary, Let me add to what Bill wrote. If you are running the wing tanks empty for the purpose of measuring the wing tank capacity then don't fill the nose tank before filling the mains. Filling the nose tank is very indeterminate because you can't tell when it's "full." If you fill it up over the standpipe, it'll hold more but the extra will drain to the wing tanks. You can't really tell when you've filled the nose tank up to or past the overflow tube opening. When you are out flying about and drain the mains and some of the nose tank, then do just as Bill said. Fill the nose tank first. But, wait a while for the nose tank over-fill to drain down into the wing tanks before you fill the wing tanks to near the top. If you fill the wing tanks too soon after overfilling the nose tank, then the nose tank's extra fuel will drain down and over fill the wing tanks, leaking out the caps. (That puts flames and explosions behind the warning "no smoking during fueling operations.") It's not really a big deal or a problem. Just be patient for a few moments. Ed
