When venting the fuel system on a case 990. After cleaning the water trap/sediment bowl and reassembled, then loosen the connection to the lift pump and bleed until free of air. Next loosen proper plug and connection in proper order bleeding the fuel filters. Next go to fuel injection pump loosen plugs in proper order and prime until air is out. All this is OK. My question is- when you start venting the high pressure pipes at the nozzle ends, do you loosen all of them at the same time and then use the starter to vent them, or do you vent one line at a time? Also if you vent one line at a time , is there a particular order? If the lines must be vented in an order, what is that order ?Thanks for any help. Steve
