I just purchased a 1969 T337. A debate is brewing as to how the aux tanks function. The articles from the previous site said you can't get the aux fuel from a NORMALLY ASPIRATED ENGINE if you run the mains dry. I have been flying my plane the way it is stated ( after an hour switch one tank and then fifteen later switch the other, etc.).

When you look at the POH from Cessna, it does show a diagram of the fuel system which shows the pumps in a different configuration than the article diagram.

Perhaps GMAS or someone can clarify the difference.

Thanks,
