I can't get any fuel through my line. I have a line out of tank, to water seperator, to primer bulb. The motor was not getting fuel so I pulled the line, pumped primer and got nothing. I replaced primer bulb, still nothing. Went and got a second new primer bulb, still nothing. All fuel lines are new, and I can blow air back through the line and get air bubbles in the tank. Still the most I can get out of the line is a dribble of fuel if i am lucky. Any ideas?
