Is there really enough fuel in the tank? Try it with a new fuel line back to the tank. If I understand you, you haven't actually replaced the line from the pump to the tank?
The hand pump may be able to overcome a leak in the line.

I have 3/4 of a tank of gas that is why I can get fuel up to the filter by sucking on the fuel line. A new fuel line would require the tank to be dropped and I wanted to make sure it was the line before I go through that effort. The hand pump could be stronger that the electric pump but I would think once you stop the pumping you would see the fuel drain back into the tank if there was a leak, but the fuel did not drain back.
