It is the SR5 guages. It just happened out of the blue. Im searching for loose/damage wiring right now. I filled up again (every 200 miles) and it went to the full mark and worked for about 62 miles then would intermittently dip then come up. Im thinking sendig unit in the tank at this point. I fill up almost once a day since i use my truck for work too. If any of you have replaced your in tank fuel level sensor who much was the part?
And thanks for the replies!
