Good that the gasket etc. is the same. Probably the pump stroke is ok.

What I was suggesting was hook up a vacuum gage to the input of the pump. That will tell you how much vacuum the pump can pull. It's a simple test. I don't know offhand how much that should be, others could tell you. One not insignificant possibility is one of the check valves got some crud in it and isn't closing properly, and hence you aren't getting enough pump suction.

If its not that, and the glass filter isn't obstructed, the only other thing I can think of is an obstructed fuel line from the tank.
