97 Ford 7.3L runs rough on the rear tank

[wrhatt]

I have a 97 Ford F250 4wd auto with the 7.3L diesel. When I run on the rear tank the engine runs rough but when I switch to the front tank it smooths out and runs fine. I filled both tanks at the same time from the same fuel station. Any idea's as to what is wrong?

the tank selectormight not pe switchin all the way to the second tank so its starving for fuel or you could have a clogged pickup or a hole in the line sucking in air just a few things to check out.

if i remember correctly, there is either a pump or filter in both tanks. one of them may be bad. that or you have a lot of junk in your rear tank.

Thanks for the suggestions, I'll try to pinpoint what I'm dealing with.

Try checking the fuel pressure on each tank.
