What was found
REMOVED RT FUEL SENDER PN S38522 SN 4688 AND INSTALLED RT FUEL SENDER PN S38522 SN 4963. WE HAVE BEEN HAVING A TERRIBLE TIME WITH FUEL SENDERS FROM CESSNA. WE KEEP GETTING ERRATIC INDICATIONS OF FUEL AND THEY QUIT WORKING COMPLETELY INTERMITTENTLY. CESSNA HAS NOT BEEN VERY SUPPORTIVE IN DETERMINING THE CAUSE OF DEFECTIVE PARTS. THERE NEEDS TO BE AN INVESTIGATION INTO THESE DEFECTIVE PARTS.
