Question Pickup Pump Problem 7.3

I have an 89 F350 Crew Cab Dually with a 7.3 and an A/T behind.

My problem is we just put a New Carquest Brand Pickup/Lift Pump on it today and cannot get it to Pump fuel up to the Filter. We removed the fuel line going into the fuel filter and attached a manual vacuum pump to it and using it we had no problem pulling fuel up. After removing the vacuum pump and turning the motor over a couple of different times, we still could not get it to pump fuel up to that point.

Hope someone can help me figure out what my problem is...
