Been having a problem when changing fuel filter. Not every time but a problem when it happens we are getting air in system. Have owned this tractor since day one. I shut off the fuel at filter, dropped bowl and cleaned out. Installed new filter in bowl and filled with fresh fuel, installed bowl and filter and opened fuel shut off allowing a small amount of fuel to run over the top of bowl and tighten lock ring. I was told to make sure that the fuel tank was at least half full, so gravity pushed tank fuel to filter and pump. I know this to work, the first time I got air in it system the tank was below 1/4. I filled tank and was able to start just before the battery gave out. I am looking to avoid this air problem...any suggestions would be appreciated.

Have you followed the procedure below? If you don't, any air has to work it's way through the injection pump, down the injector lines, and through the injectors. Takes much longer, using this procedure, I've never had a problem.
BTW, make every effort to never run out of fuel.
