[V8] fuel pump sender locking ring removal?

[Karl Middlebrooks]

Looking at the manuals didn't give me a sense of this until I got in there....

The locking ring that holds the fuel sender in place needs to come out, so I can get to the fuel pump. Having disconnected the cottonpickin' thing and looking at the locking ring, it looks like you can't just twist it off with your hands and even with a short pry bar turned sideways across the grooves, I can't get enough leverage to budge it...rather, I'm afraid that if I put too much leverage on two points of that ring, I'll foul it up for good.
