Maybe only the 4x20 uses the computational calculations? LOL...Found the sending unit for the 3x20 series cabbed machines...and I'm 99% sure its the same on your 4x20...
I'll be danged, I missed that. It's #8 on my diagram but it's indeed the fuel sender.
Now it remains to be determined which of the sender, the gauge or the computer is at fault.
