Many of us have our "niche" on what we know.

I will defer to others on any conclusive answer. However, I will say that over the years, I have seen some people live with a contribution code for quite a while, but then others seem to get bit. There are several things that can cause a contribution code, some more potentially harmful than others. If it is a failing injector, or low fuel pressure (#7 is at the end of the fuel rail), then it may become something significant enough to do other damage. Maybe if you know what to watch for it can be driven for a bit - if it has to be.

Personally, especially in an open forum, my advice will almost always be to fix things as soon as possible. The 6.0L reputation is bad enough without any help, lol.

Anxious to see other opinions!

Don't push it. Bubbles when cranking mean that the entire rail will be backing out fuel to a degree. If you had newer injectors on that passenger side, then that might hurt them. If you plan on changing them all anyway, then I wouldn't imagine a careful 30 mile drive would do any more damage.

Again - others may feel differently and I could easily appreciate that perspective as well.

EDIT - I would also say - shut it down if you start seeing a lot of white exhaust smoke.

Ford's minimum fuel pressure (at WOT) is 45 psig. My minimum acceptable value would be 50 psig. Typically it is around 60-65 psig.
