    quote Steve D:

    Pulse line plugged/restricted somehow? Or any possibility you could revert back to your original setup with a good pressure tank to eliminate all this from the equation temporarily?

    Steve, brought up a good point. The pulse line or barb coming the the bypass cover could be obstructed or partial obstructive preventing adequate functioning of the fuel pump. By pumping the the fuel line bulb you are performing the function of the fuel pump. Please make sure the in line fuel filter is not a one directional flow and installed backwards prevent proper flow of the fuel.

    edit: I forgot to mention that the pulse line coming from the bypass cover and going to the pulse port on the fuel pump can get clogged with old fuel mix and prevent properly functioning fuel pump.

    Also, a briggs and straton fuel pump can be used as a cheap substitute. I think they are about $10 to 12 bucks apiece.
