Well, I’ll tell you!
I had the need to drain one fuel tank on the Val, and decided to see if I could make some of the process easier by not having to duck under the wing and shuffle four different gas cans around. I had succumbed to that carnival barker at SnF last year and bought one of those handy-dandy siphon hoses with the valve on the bottom (I use it to fuel the jet without hoisting cans high in the air), and it worked great!
However, of course, it can only go as far into the tank as the first rib in from the tip. Seems like a long way out from the root, and taking dihedral into account, I figured I’d still have quite a bit to drain.
Well the answer is that I managed to get 16 gallons of the 21 gallon capacity out through the full valve...way more than I thought I’d get.
Didn’t leave much to drain, and I only had to duck under the wing with one can.
Just a data point for the trivia experts (i.e., other engineers) out there.....
