90 f250 fuel issues
 

I am having trouble with my rear gas tank, I am not able to get fuel from it. Before I start replacing things anyone have anys suggestions? (I am nes to this also so if there is a better way to ask for help like this let me know!)

Sounds like the in tank pump is dead or not getting power, try in the 87-96 F-series forum or go to fuel injection/ carburetion forum......If the pump is dead, you will have to drop that tank to replace it..............Not as bad as it sounds.

You said rear tank, if there is a forward tank what about the solenoid not switching the tanks.
