How do you get to this vacuum hose? I think it is the culprit of my check engine light code. Its a 1999 grand cherokee.

I'm not aware of a vacuum hose next to the fuel cap, only a large vent hose and the filler neck hose.

It's in behind the rear wheel. But I'm not sure how to access it. My son's got changed & solved his problem. But he didn't see how they got to it.

I haven't looked for mine, but my wife's Dodge Caravan's was behind the plastic fender liner just in front of the rear wheel. Those are steel and known to rot out.
