Hi, John....that is a very interesting
theory. My tanks were not full, but I assume that my sump tank is always
full, and if more fuel is returned to my already full sump tank, the fuel should
just be pushed back up what is normally the feed line and into the selected
tank. When the engine is at idle, that is the time that considerably more
fuel is returned to the sump tank. At WOT on takeoff, the engine is
consuming more fuel, so I would assume that less fuel is being returned to the
fuel sump tank, and some fuel is gravity feeding from the main tank to the sump
tank. I may be missing something here. Paul Conner, top posting this
time. It just somehow doesn't feel right to put the answer before the question.

My point was that I (twice) experienced exactly the
same symptoms as you when trying to pump to a full tank.
I understood that part....I was
just trying to determine how our plumbing compared, and try to understand what
might cause the loss in performance. Paul Conner
OK. I have simply avoided the scenario,
but my WAG at the time was that the returning fuel had nowhere to go
(quickly) and this affected the pump / rail pressure to make the mixture go
either overlean or overrich. Luckily I was at a much better spot than you, and
just descended at idle. I did try a power blip on short final and all I got
was about 2000 rpm and very rough.
