Gas tanks both run empty on 1/4 tank

Your fuel tank senders are probably the problem. They flat out suck. I have the same problem with my truck. I bought a new AUX tank sender a while back at the dealer, I want to say it was 45.00, so they are not to expensive. Any local shop could install them for you. You could replace the gauge first just to make sure its not the cause, it is a hell of a lot easier to fix then the senders. I would probably start there just for kicks, and its alot cheaper and easier to fix then the senders.
