Thanks mate....got there by opening man release valve and lifting by hand the engine at least a dozen times.....pausing at the top for ten seconds then lowering.....each movement produced an air burp.... finally pump took over and primed,then it was just a matter of allowing tiny air bubbles to come out during repeat operations to obtain correct level.....CheersFrom a 2009 DF90A service manual. Your engine is older so the screenshot might not be valid. Best I can do.
