As of know its has full tank and only has 2 bars on ! What the fix here? Thanks!

 

Could possibly be the float arm rubbing against the tank(fixed a few of those by bending the arm out a little) or fuel sender corrosion,plus if you look at the tank and the deep drop it makes I don't think I've ever seen one exactly accurate. OPT

 

Thanks how do get ahold of the float arm?

 

You have to remove the sender from the tank and slightly bend the wire arm to where the float won't rub the inside wall of the tank. While you have it out you can do an ohms check with a meter to see if ohms vary from empty position to full to see if the sender is working properly. OPT
