fuel guage not reading full, even with a full tank of gas Options

Is the float for the sender getting stuck? or is it the wiring. If i go to fill up the gas guage only shows the tank half full. Once i use the first half tank the guage works normally, untill i fill up again.

If I have to take the sender out is there a way to slow down the movement of the needle on the fuel guage? If i'm at a quarter tank and take a sharp right I can get the empty light to come on.

As for the half-full bit, it's possible the rod the float slides on is bent so the float only goes up halfway. Removing the sender to check this isn't hard. Just remove the expansion tank and the sender is right there on top of the tank. No need to even drain the tank first.

Any gaskets that need to be replaced when I take the sender out? Thanks for the reply guys.
