Needing some help.
I recently purchased a 1992 f350 dually.The guy I purchased it from replaced the return lines and filter. He also said the factory fuel tanks were not working one, he said was leaking so he put a 35 gallon tank in the bed. It starts and dies everytime I try it. I have bled the lines and still the same result. I was looking at everything he did and I do not see a return line from the engine back to the new tank could this be the problem or something else I'm missing. Thanks in advance.

Not knowing what he did to the non factory fuel system will make it very very hard to help you.
We deal in factory fuel systems so if you want to put it back to factory we will try to help you.
The OBS truck that you have was set up for a return fuel line and as we do not know the ins and outs of your system we can say one way or the other if the return line is what is causing the stall after starting.
Most of the time this would be a lack of fuel pressure causing your problem.
Does it put out black smoke when you try to start it?

No sir it blows a little white smoke on start up. All he did was put the tank in the bed and run the supply line straight from it to the lift pump. And he changed out the tee's and return lines on top of the engine. I can' find what he did with the main return line that's why I was wondering if this could be my problem. I just purchased a new lift pump to see if that is possibly the problem.

welcome to FTE.
it sounds like you are chasing a herd of feral cats.
lucky for you, i think you are also chasing the rite cat. if there is no return line from injector pump and fuel rails to the tank, the engine will not run.

i would not. what happens if the return pumps bubbles? you end up with air in the supply system.
me personally, i would look for a large tank to put in the back where the stock tank should be and eliminate all the added on crap.

Didn't think about the possibility of that. Thanks for the heads up. I'l see what I can do to get it taken care of.

Did it ever run for you?
I am a pretty good fabricator. If you post photos I may be able to see a solution.
New replacement tanks are available cheaply.
