2FBF... Among the 02 codes

Well, I got a SES light yesterday (due to 02 related codes; I've been getting them for months)

The SES light bothers me along with the car driving differently when it's on..

Now, the thing is, I've had 2FBF for a little while (about 1000 miles) without it throwing the SES light

Thing is, when I wanted to clear the 02 related codes, I had to also remove the 2FBF

Now does that mean that once I stop being lazy and take out the JB3 so I can go to the dealer that they won't see the 2FBF thus making my trip (and effort to remove mod(s)) useless?

I've had misfires in cyl 2 and 3 whenever I ran anything over Map 3 on 91 octane (even though I'm modded)

So I did want them to fix those.. but those were cleared and well, due to me not wanting Misfires, I've been using Map 0 and the occasional map 3

Will the 2FBF come back? (it had 3 events of it)

Or can I go and they'll change the fuel pump without it?

I've been turning my car 'on' for a good 30 seconds to a minute before actually starting it, and I've noticed a substantial decrease in cranks
But last thing I need is for the fuel pump to go byebye while I'm driving hard etc...

Thanks

P.S. I did a search, but couldn't see one where anyone had 02 related codes along with fuel pump code and also needing to get rid of them etc
If I missed a thread about it, then I am sorry
