Good morning, I have a Case Cx80 and can not seem to find issue with secondary fuel filter keeps pumping down to around the one third level. Completed priming multiple times. Flushed fuel tank, blew out lines, checked to see if it was sucking air somewhere at primary filter, replaced lift pump, and filters. It will stay full for a littler while but will just pump down after awhile. It has to something between secondary filter head and primary filter assembly. Only thing I can think of at this point is replacing primary filter head assembly. Looking for anyone else who might have had this issue.
Does the machine run good through this?
yes, machine still runs ok.
