Flair Nut Wrench

I'm trying to remove my fuel lift pump (F-250, 7.3) and the nut on the line out is stuck. I've tried using a regular open end wrench but not having any luck. I've heard that Craftsman flair nut wrenches spread open, can anyone recommend something that won't break the bank, S-O, Mac, etc...

As you said, snap on, mac, even craftsman. One of the tricks is to TIGHTEN the nut slightly before you try to loosen it. Greg

I was going to tell you to gently heat it a little until I noticed it was a fuel line. That would probably be a bad idea in this case. It will help loosen up a stuck flare fitting most of the time because of the drastically different expansion rate of the metal used in the nut.
