There is a Fuel Tank Screen and there is a Primary Filter. I am not 100% sure but I believe in your case the little Primary Filter (pre-filter) is built into the Fuel Filter Housing.
Looking a what a parts seller has if you have the Primary Filter as described you need an O-Ring and the Filter itself has a Rubber Seal on it.
And last there is the Spin-on/Secondary Filter.
You have no Hand Primer like the Older Modes have so be sure to fill up the Spin-on Filter with as much clean Fuel as you can to decrease the amount of Engine Cranking you have to do to clear the System of Air.
If you have an exceptional amount of trouble starting after a filter change loosen the Fuel Injection Hard Lines at the Injectors and crank to bleed the Air out of them and then retighten them.
