You're a fine person, Mark. I also am pleased
when I am able to help a fellow aviation enthusiast. Paul

Paul,
No big deal.
I’m happy to be able to give it to someone that can use it. You can
repay me with a ride in your SQ2000 (once you get the kinks in the fuel system
worked out).

Hi, Mark....yes, the brochure
arrived today. Thank you so much for finding and sending it. I would be
pleased to reimburse you for your time and shipping. Please advise off line,
and I'll be happy to reimburse you. There was a lot of info in there
that I was not aware of. Lots of fun looking at it. Thanks again.

Hi, Mark....that seems to be the
general consensus, and I agree that it is the most likely cause of the fuel
starvation. I ran the aircraft several times yesterday, and it still
ran as smooth as ever. I tried a couple of aborted takeoffs, and it
still ran great. Good acceleration, nosewheel off the ground by 1200
feet. Unfortunately, until I vent the sump tank and install
firesleeving on my fuel lines, the nosewheel is the only part of the plane
that is going to leave the ground. Will keep you posted. Thanks
again for your input. Paul Conner, off to the
welder

Paul,
It looks like the
group has focused in on the fuel system, or more specifically the sump
tank as the likely culprit. I suspected you might have been running
mogas. Its my understanding that auto fuel has a much lower vapor
pressure than avgas and is therefore more likely to vapor lock.
Just a SWAG, but
I think the engine and related systems got hot enough to heat the fuel in
the fuel rails so that once it passed the pressure regulator (pressure
drop) it started to boil, similar to when you open a hot soda. With
the return fuel going to an unvented tank, the boiling fuel expanded
enough to cause pressure in the header tank so as to prevent fresh fuel
from flowing into the tank. Eventually, the header tank ran dry and
the engine quit. You sure handled the situation like a pro.
Hope I never have to face that
scenario.
Mark S.
Hi, Mark...my humblest
appologies for taking so long to respond. I am whittling down the
200 plus messages in my inbox. I was using auto fuel (regular). I
have a fuel return line and it goes to the top of my aluminum sump tank
that is located on the cool side of the firewall (inside the cabin, behind
the rear seat). The return line is -8 in size. Hope this
helps. Paul Conner
