Try another tank and line, as a troubleshooting tool. The lines are well known for collapsing inside; and if using a plastic Quicksilver tank, the pick ups in the tank get loose and suck air, even kink themselves off. If you have two Quicksilver tanks, be suspect of both of them. I see that all the time, lately, with the ethanol.

Long live American manufacturing!
