I disagree with a few things above. Do not pre-fill filters more than half way. You can end up with an air slug that gets forces into the high pressure side of the fuel system. If you do that you will have to bleed to air at the injectors as well. If you properly bleed the low pressure system you don't have to bleed the air from the high pressure side during a filter change.

The squeeze bulb isn't necessary at all. The manual lever on the lift pump actually pumps more than you would think based on feel. I don't pre-fill my filters at all and it really doesn't take that much pumping to fill the Racor primary and the engine mounted secondary filter.
