fuel gauge

Ok, first real issue, seems that fuel gage does ot work correctly. I have ran out of gas twice, first time was about 1/4 tank, and 2nd time was about 1/3 of a tank.

Assume that is fuel pump or sender?

thanks in advance.

Go to the auto parts store and get 2 bottles of 'Techron Fuel System Concentrate' Add one to the tank at next fill up, let it get half way down and add a second bottle and fill up again. GM sender units are known to stick. I did this trick to my old Jimmy that had 230k miles on the clock and it fixed the problem. I now add a bottle add every oil change to all my cars. Techron is reccommended and used by BMW, Mercedes, Hyundai, to name a few. Good luck
