Engine started bogging down when under a load, but would start back. So I changed out the fuel filter, but it started quitting every couple of minutes even when it wasn't under a load. I'm getting a lot of air out of the fuel filter bleed off when I pump the bulb. I've bled the injector connections to let air out but I can't get rid of it all. I wonder if after changing out the fuel filter and pumping the bulb that it may have made the pickup tube crack. I can hear air blowing in the tank when I pump the bulb. I've searched the forums and read about a lot of trouble owners have had with this fuel pickup tube.
