I have a 1993 Tracker Magna DC and a 2003 Johnson 90hp 4strk with a 27-gal under floor tank. My question is that I can't get the bulb to pickup fuel out of the tank. I've replaced the vent, fuel, and line with bulb and new connections to tank. I removed the pickup tube inside the tank and the screen was free and clear of any obstructions. Is there supposed to be a spring and ball in either fitting above the pickup tube because I can see through both of the fittings and the pickup tube. Thanks for any input on this.
