Is this an indication of something failing?

:snipersmi Probally won't get a response callin it a gas gauge on a diesel site. IT'S FUEL!!

Rough road and worn shocks.

When I R&R'd my sender unit it was broken, as was the new one I was putting in. The armature that holds the float is held by cheap plastic clips that are easily broken. I wired mine up before installing it, in order to repair and strengthen it. Prior to the R&R my fuel gauge was really eratic.
You should fillout your sig so we know what you're driving. Then it's easier to help.

My swings from time to time usually under a qtr tank. Hate when that happens...I dont want to run it dry!:eek:

lol someone beat me to it I just saw this thread, I was gonna say thats your prob you got a gas gauge on a diesel....

It could be bad chassis grounds too...these trucks are plagued with electrical issues...

fysh guide - i have to repair my sender as well. It was "bouncing" for a while then it finally landed on "full" and never moves (i checked the ground well and am sure it is the sender).
could you, or anyone, explain in a little more detail how to fix it?
on mine, i don't think the thing that holds the float is broken off (i checked it out) but rather there is a bad electrical connection somewhere in the resistor. Can that be fixed? I know there is power going to the sender.
thanks,
paul
