Since pumps push better than the pull, the fact that it fills the bowl says your pump is OK. The problem is between the pump and the engine. In most cases, electric pumps are just band-aids. After I finally figured out what was going on about 25 years ago, I removed the electric pump from my '51 and never looked back. The stock pump is now supplying a Rochester 2G with twice the capacity of a stock carb just fine.
Rather than wasting money on an electric pump, have yours rebuilt properly by Charlie Schwendler in New York; you won't be sorry. (Send your carb with it.)
BTW, Ford carbs like 1.5 to 2.5 psi fuel pressure.
