Issue worsened. Engine (Mercury 40 EFI) was starving and the fuel ball was collapsed. Had mechanic look at this and after contacting West Marine he cut off the fuel mechanism on the wall and ran the line direct from tank to engine. Then he cracked the fuel cap in order to vent the tank. This is a 12 gal Attwood plastic, unvented tank. I had already replaced the equalizer and the fuel line and still had the problem. This was after cleaning and rebuilding the fuel pump and the separator. Very expensive solution for an unvented tank. For the sending unit, I finally just unscrewed the gauge at the tank, used plastic epoxy to put the sending unit gasket on the tank, ran a pink electrical line to the new gauge on the console and connected it to my new fuse block. We'll see.
That brings me to my next problem. Want to add a tach, voltmeter, and tilt gauge. To do this I need to access the wiring harness that terminates at the remote throttle on the right side. I assume I remove the throttle and then the panel that hides the electrical harness and steering cables. I cannot determine how to do this. Anyone been through this with a Lund 1625 Fury XS?
