Two problems, apparently caused by brush snagging the wiring.
One, is a leak has developed around the fuel guage sending unit at the base of
the tank. It looks like I will have to replace the entire unit. The second is several wires in the same vicinity are unplugged. Does anyone have a schematic that would show how the wires should be connected? They are not color coordinated as far as I can tell.
Thanks.
 
No cab, so probably is accessory plugs. Still interested in sending unit information, looks to be leaking around seal.
 
Could have cause by poor conductivity or moisture around the wires, better to replace the whole set to make it work better. When changing wires in a harness make it in set, it's because when you cut the wire and you connect a new one it could affect the impedance and that's when the reading start getting wrong

The sending unit must be replaced. JD pressed 2 plastic parts together and expected them to seal. Vibration and general use causes the 2 parts to lose their seal. I had to replace the unit on my 5105. About $130 from JD

I tried to use a diesel proof sealant but it didnt work
