Is it like this all the time or just after a fill up?

 

[silsbeeman]

all the time

I don't know for sure but if it was me I would probably try the sending unit first. My gauge does that right after a fill up and doesn't come down to full (while running) for about 60-90 miles. So it doesn't seem abnormal for the gauge to be there but that it is always like that. That would lead me to suspect that that sending unit is always reporting full to the gauge since yours seems to be behaving exactly like mine when mine is full.

Have you guys pulled the needles or swapped in clusters?

i just bought the truck a cpl months ago. i have no idea if he pulled needles or its a new cluster. i was thinking that might be where the problem is.
