air in fuel system peugeot 106 diesel?

have you disturbed anything? I have found on pugs in the past (205 XUD7, 306 XUD9 and 406 XUD11) that the fuel filters are generally the culprit - try replacing the filter element in case the rubber seal is giving up, wouldn't hurt to use liquid gasket when you re-assemble and leave it 24 hours before re-priming fuel system. Also check the banjo fittings on fuel lines, replacing the copper crush washers, but DON'T tighten them up too far - use a torque wrench - as the bolts have a habit of shearing due to being hollow. Best advice for finding leak is work from the fuel pump backwards. Remember you won't nec essarily see fuel leaking out as the lines are under suction from the pump!
