Charlie,
My experience over the past six years/1200 hours in my IV-P closely paralle=
ls yours. I believe our aviation fuel supply system is much "cleaner" than =
it used to be, and my wingtop gas caps don't leak--water...a problem with l=
ots of airplanes. So after a couple of years of catching just a few bits an=
d pieces in the gascolator, it's been completely clean.

Still, it only takes one time...so I'm staying with the gascolator. The gas=
colator filter looks like it wouldn't catch anything smaller than nuts and =
bolts, but it's a proven device over many years of aviation use. There are =
definitely better filters available, but they have drawbacks/limitations.

Bob

Data point for gascolators:

Legacy IO550, unheated hangar in Dallas (variable humidity, but on the dry =
side), fuel from municipal self-serve pump, and from self-serves whenever p=
ossible on cross-country.

1.  Have never seen water or sediment in the wings.  Dunno why not.  Other =
planes at same airport -- pretty much same deal. =20

2.  Never seen water in the gascolator.  I check it at every oil filter cha=
nge.

3.  After build, the gascolator trapped on the screen some grayish fuzz and=
 in the bowl small soft gray bits of ... proseal? ... in diminishing amount=
s over the first 150 hours / 1 year.  After that -- nothing. =20

4.  In spite of having a gascolator and taking all the same precautions tha=
t people mention -- wing sloshing etc -- an injector plugged at about 18 ho=
urs during Phase 1 testing.  Was there debris in the fuel lines *downstream=
* of the gascolator?

I don't trust fuel supplies, and I don't *ever* want an engine failure (esp=
ecially in a Lancair), so I'm keepin the gascolator.
