My IO550 Lancair Legacy has been down for about 6 months.  Before flying I need to fill and test the gear on the ground.  The lines were disconnected and I need to insure that the system is full of fluid and there is zero air in the system.  Can someone give me a procedure to refill my system properly before I test the gear?  What fluid is recommended?
