Aux Fuel

[jcthomas]

Well, I am glad I put this question out for us figure out the problem. I have examined the turbo fuel diagram in the Cessna Service manual. I do not believe there is any excess fuel being dumped back to the mains. Examining the diagram, it appears the excess returns to the manifold and is used. This is my humble opinion.

I have already lost one dinner on a bet with my partner on this subject. I am going to try a test tomorrow. I am going to fill all of the tanks and start the engines. I will switch to the aux tanks and see if any excess fuel will be dumped over. I need to see if it is true that it the excess goes back to the manifold or does it go back to the mains.

Maybe I should wait to hear from some of you before I try ths. Of course, I will do this on the ground.

Let me know your thoughts.
