Congratulations. Without a filter, gravity with a couple of feet as a head should provide plenty of fuel pressure so unless you were running fuel thru the typical ceramic filter Packard used I expect you still have a carb issue you need to sort. No idea how much pressure a lift pump will supply but the stock mechanical pump on the engine puts out about 4 1/2 psi. Those old carbs cannot accept much more than 5 or 6 psi at the carb inlet or pressure will overpower the inlet valve operated by the float and gas will pour into the carb and then leak down into the manifold.
