I have a 1993 Jeep Grand Cherokee and it's consuming a lot of gas. I fill up and drive back home and the tank is back empty; I've checked for leaks and I have none. What could be the problems.

look on your fuel rail and pull the vac hoses off the pressure regulator. Is there any gas in there? If yes replace it and do an oil change before you drive it again!
