'71 250 fuel issues

[Craig Crowl]

I have restored this sled. Completely cleaned fuel tank, installed new fuel filter, new pump gaskets, rebuilt carb, etc...
Put it all back together and I can spray fuel into carb and it will run. I cannot get fuel from tank to carb. I dissconnected the primer line just past the fuel filter and blew into tank to push the filter full of fuel. I then ran the sled with everything hooked up and putting fuel into carb hoping that the fuel would get picked up into the pump. It still will not pull fuel to carb. Is thier another way to prime this system? I am thinking that since the fuel pump does not have fuel it will not suck the fuel up from the filter. Any ideas???

Make sure there are no leaks anywhere, especially the pulse lines between the cylinders and pump. If everything is clean it should run. Maybe try priming the pump with a syringe.
