His words, not mine...lol
Truck is 1000 miles from me so the only info I have is what he tells me...
so far it's; "The fuel gauge has gone crazy....reads whatever it wants anywhere from empty to pegged pasted full regardless to what is actually in the tank. the trip range indicator seems to correspond to whatever the gauge reads. The rest of the cluster appears to be working okay."
Anyone see this before?
I'm searching the forums...
His '03 is 100% stock....nothing has been done to it!!!

Bad sending unit. Not sold separately last time I knew, but that may have changed.
