If air gets up into the Fuel injection lines between the IP and The Fuel Injectors it takes too much cranking with the engine to purge it. As I said if you loosen some of the Fuel Injectio Line nuts up by the Fuel Injectors ie bleed out fast.
Check this PDF below to see the factory method of bleeding the air out after a filter change:

Great, thanks. I'll do this tonight. I pumped before starting the car, a lot. The prefilter filled with fuel and the pump became hard to move, so I thought that was sufficient.
