Kevin,
I have know idea why EFI filters cannot be used on the low
pressure side as long as they do not restrict flow. Hopefully someone will chime
in with the facts. I am planning on using EFI filters before my pumps also. They
are the same ones that Ed and others are running on the high pressure side. They
have a large 16mm in and out. AC Delco GF652. I believe the Egg subi's are also
running these filters on the low pressure side.

I suspect that my engine problems stem
from a design flaw, rather than a blockage. I normally never run my engine
full power, full rich, but have been while breaking in the new rings. even
leaning the engine a few notches prevents my problem, so it never arose in the
past. my auto fuel filters are on the "suck" side, between the tanks and
the selector valve. they are small, glass see-thru mesh filters. I
realize now that all the fuel passes thru a pair of like 1/8" holes from a
common 1/4" passage. I also see that the facet pump, despite pumping 15+
gals / hr with no head pressure, will only produce 1.75 lbs pressure when
attached to the carb and bypassing the manual pump.
my question - I was
told not to use a fuel injection filter on a low pressure system like
mine. I would like to keep the filters where they are rather than moving
them to the engine compartment, since they filter stuff ahead of my flow meter
and pumps. I like how they fit along the wing spar below my knees. I
had problems with the replaceable filters shedding fibers into the carb, which
is why I changed to the mesh filters. does anyone know what I should
be using?
I plan to do more
testing this weekend if my wife will let me drive her car("no, I'm not feeling
sleepy :-)" to get to the airport.
