What was found
ON CLIMB OUT, THE RIGHT FUEL TANK WAS 300+ POUNDS LOWER THAN THE LEFT. STARTED TO DO A CROSS FEED FROM LEFT TO RIGHT. SHORTLY AFTERWARDS WE RECEIVED A FUEL PRESSURE LOW RIGHT CAS MESSAGE. THE CAS MESSAGE STAYED ON FOR APPROXIMATELY 5 TO 10 SECONDS, THEN WENT OUT FOR 5 TO 10 SECONDS, CAME BACK ON. THIS REPEATED THREE TIMES AND ON THE FOURTH TIME WE GOT A LEFT AND RIGHT FUEL PRESSURE LOW CAST MESSAGE. NO ABNORMAL ENGINE INDUCATION WAS NOTED. BY THE TIME WE GOT THE CHECKLIST OUT THE CAS MESSAGE WENT AWAY AND DID NOT RETURN. WE ELECTED TO DIVERT TO SAN JUAN. RESET BREAKERS. OPS CHECK GOOD. IAW AMM 28-20-00
