Take a Weatherhead 3 way valve drill through one side of the ball so that it's now a tee rather than an ell. Now plumb so that you have a 172 standard left, right, both, off valve. If you need to use all the fuel in a tank you can dial in that tank, suck it dry and move to the other tank without losing the engine while making the transfer. It was not the brightest day but it did get me home.

Reference Far 23.951 Essentially no low wing aircraft may have a both fuel position for the fuel select valve. Same case for our Kolbs engine above fuel tanks. The intent is that we not be able to run one tank dry, suck air in the dry tank, and not figure out the error before a fuel starvation landing event.
