Okay, you have the different style primer pump, so I can't say for sure, but in the third picture...with the arrow pointing to the primer pump...there is a banjo bolt on the side of the primer pump to which a fuel line is attached. The other end of that fuel line should eventually disappear under the car and go back to the tank. If you need a pre-filter, this is the fuel line that should have it. It goes upstream of the primer pump to protect it.
However, I don't have the same kind of primer pump as you, so I can't say for sure if you have/need the pre-filter...I assume you would.
