My fuel gauge drops off when I acceleraite but returns after i roll off a bit. At highway speed i roll on and needle moves to the empty side and then returns. I know not to trust the gauge but this is bothering me. Any help here?

 

Normal, gas moving in the tank.

 

If the needle swings pretty fast, then your gauge has lost it's dampening effect. A new gauge is in order!
Had to replace mine this year.

 

+1 on this.
