Welcome, I'm Chris (aka Moose). I normally log in after 3 pm central. Please make sure to let me know exactly what is needed from me so I can provide EXCELLENT 5 STAR service. So you ran the rear tank empty and now when switched to the front full tank you could not get it to start?
Customer: replied 1 year ago.
to the best of my knowledge there is not a switch to change tanks the system is supposed to automatically switch or transfer fuel from the rear tank into the front tank supposedly. but I don't really understand how it works

Thanks, ***** ***** setup, it will not have a switch. The transfer pump will refill the front tank from the rear tank when the front tank gets below 16.9 gallons. The fuel pump sucks from the front tank. So if your concern is due to running out of fuel to the engine then its your fuel pump to blame, not the fact the rear tank as empty. Do you know how to test the fuel pump power and ground and pressure? -------------------------------------------------------------------------------------On your screen you should see a rating 1-5 stars. Please make sure to select one. I am not compensated by the website unless a customer rates. Rating only pays me from the deposit you have already made, it does not charge you more, nor close the post. Also all follow ups are free and welcome.Thanks Chris

Help me understand why it get diesel only from the rear tank and not from the front. Is the fuel going from the front to the rear and then to the motor? Everything I've read online, says the opposite.
Expert:  Chris (aka-Moose) replied 1 year ago.
The fuel goes from the rear to the front then to the engine. The rear tank always keeps the front tank full which makes it kind of look like your running the engine off the rear tank because its the only one draining down.
Customer: replied 1 year ago.
so how does the motor get fuel, if the fuel pump in the front tank doesn't work as you diagnosed
Expert:  Chris (aka-Moose) replied 1 year ago.
If the fuel pump has failed, the motor will not get any fuel. I have not diagnosed this as a no fuel concern. We have to check for power and ground to the pump and see if there is no pressure from it prior to confirming your truck died from no fuel.
