Theres 2 lines coming out of the fuel pump .theres no fuel coming out of the one going to the metering cicuits. Shouldnt fuel be coming out as you turning the motor over to start?

If it runs when pushing in the key , the fuel pump is working fine.-----You have a blockage in the carburetor !!

But why is there no fuel coming out of the other line of the pump?

The fuel pump only has 1 outlet.----The electric primer is a valve.-----It is NOT a pump.
