REFLECTOR: Fuel Filter

[Laurence Coen]

Scott,

A gascolator works differently than a filter.  It depends on gravity to 
separate the water and particulates from the fuel. the screen will catch 
floaty stuff like lint and that's about all.  Water is not a problem on a 
Velocity with the center sump arrangement so filters work fine.  The filter 
has to be able to stop anything that could plug an injector and I don't know 
what size that is but I doubt that 200 micron crud would be OK.
