two aux tanks and two tip tanks.

I have a Comanche with mains and auxes, but no tips. The first thing
I'd check in your setup is the tip tank pumps. My understanding is that
when you have tip tanks, you fly the auxes down, then pump in from the
tip tanks. Perhaps some misoperation of those pumps could affect your
fuel flow.

Also, try operating the fuel drain in the various settings. Do you see
bubbles or excessive flow from the drain when the auxes are selected?
