I think you'll find this dictionary definition very clear:

fed up

[Aleaf]

I am fed up with the persom I met every so often.
I am disgusted with the person I met every so often.
The two sentences are almost the same, right?

I would say that being fed up and being disgusted with someone are two different things -- not just different levels of the same thing.

Being fed up, in my mind, is typically associated with a temporary condition -- an expression of frustration at current situations. On the other hand, being disgusted with something/someone reads to me as having an almost physical, highly unpleasant reaction to something/someone.

Examples, I am fed up with my coworkers who do not do their jobs.

I am disgusted by an unkempt home.

According with the dictionary:
fed uP: having reached the limits of tolerance or patience with somebody or something
