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 possible 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 =
change.

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

4.  In spite of having a gascolator and taking all the same precautions =
that people mention -- wing sloshing etc -- an injector plugged at about =
18 hours 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 =
(especially in a Lancair), so I'm keepin the gascolator.
