You need to look under the truck and make sure you have two tanks. For example my truck HAD two tanks and still has two doors and two fillers. But I took the front tank out because it started to leak and I never needed both tanks. So better look first. You should have a switch beside your heater controls to switch the tanks from front to rear.

And it would probably be a good idea to check what you have in the tanks once you have verified they are there. I'm assuming this truck is new to you? I would slide a hose connected to a hand pump down into the sumps and draw out a sample. Is it varnish like smelling? Dirty with rust? You don't want to be flipping the tank switch ***** nilly without having checked or with the assurance of the PO.

Definitely check that 2nd tank for bad gas before you flip the switch. Even removing the gas filler cap can give you an idea if the gas in the secondary tank is bad. Once it turns to varnish, gas is pretty stinky.
