Is the pump mounted near the level of the bottom of the tank? If the pump is at or below the lowest point that the fuel is in the tank, the feed line to the pump would be a siphon and should present very little resistance to the pump. Pumps are must better at pushing than at pulling. I would also double check your fitting to be sure there is not an air leak.
