Is this the oil pressure gauge? Would I be able to reflange it? Pretty small line. I have line wrenches, but it's too rounded.
Can't tell from your picture. Where does the other end go? If it's also a similar fitting, you can replace the whole thing. All the fittings and tubing would be available at a hardware store. Like I suggested, vice grips will get the fitting loose, or grind it completely down. I'd be surprised if vice grips won't get that loose.
