REFLECTOR: Fw: Fuel Filters

[Douglas Holub]

I've got a glass filter between the sump and the electric fuel pump and was 
surprised to see an accumulation of gunk after the first 20 hours of flying 
time. The gunk looked liked fiberglass dust. I figured the gunk would stay 
at the bottom of the sump, but it didn't. I think I'll look into one of 
those filters with the built-in bypass. In the meantime, I'm keeping an eye 
on that glass filter. I'm actually more worried about it clogging up than I 
am about the fiberglass dust getting into the engine.
