gas gauge always goes to full?
 

the needle on my gas tank level gauge pretty much stays at full and doesn't really move unless i put gas in it then it will drop but eventually will rise back to full. anybody know whats going on?

I would say you have a bed fuel level sender, it is corroded or the fuel level float is stuck at the top.

I have a similar problem with my car, If i put put a full tank of gas in it, the needle will go to 3/4 tank and then slowly sink down to a little over 1/4 tank. I have never taken it apart to pinpoint the cause. It could possibly help to go after the connecter for the sender with some CRC qd electrical connection cleaner. I do not know myself if the connector for the fuel pump and the sender are in the same harness or not.

mine is stuck all the way up, the low fuel light still works though so i know when to refuel. it used to go up and then come back down, but one day it went above full and stayed there.
