fuel pump push pull question school me

I have run the blue and red pumps before on cells like yours, yes.

Ok, I will proceed with what I have then.....I have one of those see-through clear filters up by the carb and it is about half full at start up but after running it about 20 minutes in the garage , it is near empty....Just barely seeing fuel sputtering in the bottom......Although the motor hasn't stalled or stumbled.......As you can tell from my pics, It is going to be awhile until I can actually get it on the road and see what it does....I was just trying to save myself a headache down the road......
