All the crap in the fuel tank may be preventing the fuel to flow.
If you can feel resistance on the down-stroke of the primer pump it should be pumping fuel.
No fuel should be coming out of whatever you are referring to.
Crack the injector lines again one at a time. Pump fuel until air bubbles come out with the fuel. Then pump until there are no air bubbles.
I used to apply air pressure to the fuel tank filler cap. The vent hole.
I rarely used the primer pump.
I changed so many fuel filters when I ran a service truck that I knew the (Cat) filter part number for every piece I worked on. It was a bunch of them (machines).
