I have an 89 super cab F-350 2wd 5-spd with the 7.3, and I have been racking my brain trying to chase rabbits with this thing. First it was the over heating, then the alternator, then the glow plug controller, now I think I'm not getting enough fuel.. It cranks up easy, idles like a brand new one, but when I start driving it, the truck starts running really rough, it gets that "hard diesel sound" then it starts shaking really bad then I loose power until it cuts off. When I try to start it again, it acts like its out of fuel for several mins. I have replaced the fuel filter, I have bled the valve on top of the filter, and diesel pours out, never any air. So now I don't know where to look, this truck is all stock no mods at all with 73000 miles on it, if I can get it running 100% then I will start adding fun toys and parts to it but until then... I lost!
So today I thought to switch from the rear tank to the front, and I babied it up and down the block a few time, no problems, then I picked up the pace until I was driving it like some sort of hotrod... Still no problem, so I think that it may just be a problem that's isolated to the rear tank, any ideas?
How much fuel is in the tank(s). The pick-ups breaking off are a known issue and can give you no fuel symptoms at about 1/4 tank. Another possibility is the selector valve not fully seating in one direction.

I'm not sure as to how much fuel is left in the rear tank, I do know that I have been running off of it for a while... So it sounds like I need to pull the bed and check out the pick-up , and maybe the sending unit...
