Narrative:
FL340; upon level off left engine fuel filter EICAS message appeared. Declared emergency and performed checklist. Called dispatch and maintenance. On return to our departure airport we dumped approximately 110;000 pounds of fuel to max landing weight EICAS message kept reoccurring. Also fuel schematic showed left wing tank pump pressures both blanking out. Landed with equipment standing by. I was notified prior to departure that left engine fuel pump had been replaced the night prior.
