Fuel filter being a pain... Options

[Box]

Yes I searched and found the write up on it, but it barely made mention of the banjo bolt which is causing me nothing but grief. It won't break free. The top of the filter actually caved in before the bolt has given any. Have sprayed it with WD-40, still nothing. Have removed the air box out of the way so I have plenty of access. Using a 6 sided 17mm socket on a 1/2" drive ratchet, it's not slipping. Keeps flexing the filter. It is the ORIGINAL filter, so it's been in place for the last 17 years. Is this just a case of seized stubborn bolts, or is there something I'm overlooking? Don't like to be a bother, but I don't want to go any further and end up damaging the banjo bolt and line if there's something I'm overlooking. Changed the fuel pump strainer earlier, the fitting on the send line was a real pain. Finally got it to break free though. Here I thought the fuel filter was going to be the easy part... Thanks for any help that can be provided.

easiest way i found was to remove the bracket from the filter than use two wrenches, one to "turn"the filter and the other to turn the bolt. I say "turn" the filter cause your not really turning it (you dont want to break the fuel line) But youre holding it in place and slightly applying force in the opposite direction when you are trying to loosen the other bolt
