Aux Fuel
I own a 1969 T337. While flying on the aux tanks, went a little longer than one hour and heard the front engine begin to suffer from fuel exhaustion. Switched tanks and everything went according to plans.
Question which is being debated is, Why in a Turbo with 18 gal aux tanks do you only get one hour of fuel? Keep in mind that the diagram of the fuel system in a Turbo is different from a NA 337. The diagram does not show the excess fuel returning to the mains. Further proof of that is when we filled the aux tank each only took 13 gallons, meaning there was still 6 gallons in each tank.
My partner and I debated this issue and his logic seems better than mine. I always thought the excess retuned to the mains, but it doesn't. The proof is that upon fill-up of the auxs' they only take 13 gallons each.
Anyone have any ideas or know more about it?
Thanks
John
