My gas gauge just started to move from full to about half a tank, then back up to full, then back down and back up etc. It does this slowly, truck has about 170,000 and this has never been an issue until today. Did a lot of gravel roads today and hit some one hole that shook things up, but that is not unusual.
Any ideas what I should check first? All other gauges work fine.

try a steady dose of techron fuel treatment for 2 or 3 tanks. it has a 50/50 chance of cleaning the sending unit.
