I think Al is referring to in-tank filters/pumps found in
most automobiles these days.

Yes, it was the high side filter. I don't have any low side
filters. Would be interested in a source for the self-cleaning fool-proof
low side filters that Al mentions.

So for the record, was it the inlet side or the high pressure side
filter that clogged? ( Both are needed ) From the symptoms I'm guessing
high side but not sure.
BTW, nice job!

As long as your are rebuilding, tremendous safety improvement by using
same fuel filter method that all cars use. No matter how much foreign
material you throw at it, it can't clog. It minimizes pressure
drop, so lower risk of vapor lock. Self cleaning filter. Self priming pumps.

Dave, having gone through recently what you just experienced I would
like to say GOOD JOB on getting down safely and with such little
damage. Anyway at 1500 AGL there isn't a lot of time ... obviously
you made the right choices.

Sigh..
Yup, that was me. I have been meaning to fess up.
We were at about 1500 agl when the fuses blew on my fuel pumps. I
was in a close formation of 40 aircraft at the time too. I think I
got some bad MOGAS somewhere in Iowa as I did notice my fuel return
flow creep downward but didn't think it was a big problem.
On the incident flight, a one hour formation flight from SQI
for a mass arrival at OSH, the return fuel flow drifted down to
zero. I actually though it was a sensor problem. I didn't have the
ability to give it a lot of attention because we were in a loose
formation. Soon after we pulled it together for a tight formation
power switched off. I tried to find a road, but quickly ran out of
options and put it down in a bean field. With the beans hitting the
flaps it brought me to a stop in about 200ft, just before I would
have gone into the full grown corn. As mentioned, wheel pants broke
in half but no other damage besides pulling bean leaves out of every
nook and cranny. The farmers were very nice, and the stories are
true... they have attractive daughters. They were out there barefoot
in their Sunday best enjoying the excitement. Helped me clean the
fuel filter and replace the fuses. Within a couple of hours I was
able to take off from one of their driveways as they all waived good
bye (but strangely, no one took me up on my offer for a
ride).
Landed at OSH just before dark to a reserved parking
space and a very warm reception from the formation group and
friends. Great support from everyone all around, though I am trying
to avoid the obvious new call signs they are trying to give
me.
