    Need a quick easy cheap do it yourself way to turn off or otherwise isolate the passenger fuel tank from sending or receiving fuel. I would like to run off the drivers side tank only for a week or two to test a theory.

    Depending on the make and model, you may have valves in place to do that, look under the cab and trace the fuel lines and look for valves. remember there will be two valves per tank, to the fuel pump and return back to the tank.

    OK I took the side skirts off the truck and crawled under there tracing the fuel lines whatnot. The only 'valve' I could determine would be a box/manifold type of thing behind the transmission where both tanks' fuel lines connect into then 'out' lines to the engine. I rooted around with my fingers all around it, but could not feel anything that would seem to be a shut off valve. I couldn't get in a better position because of the truck idling to keep the dog cool plus I burned my arm on the DPF filter. I will call a shop and ask if they know but looks like the solution may be to disconnect the fuel lines from the top of the passenger tank, cap the lines and cap the connectors at the tank too.

    Problem I'm having is, as the truck leans to the right all day most of the fuel ends up in the passenger tank then the fuel gauge will show dog empty with red light even though I know there is about 6-8 inches in both tanks-- about 1/4 tanks or 250 miles range. I tried to outsmart the fuel gauge once, knowing there was plenty of fuel but the truck shut down on me and it cost $280 bucks for someone to come out and put some fuel in. I estimate I've been putting in about $350 to $450 too much in fuel every week that should go to my paycheck. I just want to stop the bleeding for a couple weeks til I can get the thing in the shop for a true fix.

    The manifold that you described above the transmission is where the valves are, they usually have rods coming off of there over to the area above the drivers side fuel tank in the space between the fuel tank and bottom of cab. The rods are turned on the ends to form a handle to maneuver the rods for shutting them off or turning them on. It is common for the manifold to not have valves also, so if you didn't see the rod handles coming off the manifold going to the drivers side, then your truck doesn't have valves, which would mean plugging the lines and tank ports would be required to stop using the passenger tank.

    As the fuel line hoses get old they soon are not air tight due to drying out and cracking, and this causes the problem that you describe. You might also check the vent in each tank to make sure they are not plugged as well.

    Not all have shut-offs, my current ride does,but the 2008 and 2005 Columbias didn't as well as a 2001 lightweight FLD, and the shutoffs have varied from rotary to the push pull levers, which usually worked both inlet and return lines to the same tank at the same time. I had one with the handles missing but could shut it off by pulling the valves with a hook.

    From your description, I'd say your truck has no shut-offs.
