Restricted fuel supply:

I was using one in my kero supply tank, worked fine when new..after a period of time pumping / air bubble problems showed up in the fill line. Cut it off added a different large port brass clunck added some nylon stocking material for filtering.. problem solved. I believe the orbit filter screen material causes too much restriction..which causes pumps to pump slowly and pumps don't like that!!!

I never have used one in the aircraft fuel system...switch to a UAT for the final draw tank, use open brass clunck(s) in your tank(s)..your problem will go away.
