ANYTHING that seems to work for you to help loosen it. WD40 ECT. For starters. Just check and ask at a local parts store really, because there are better availiable. But:
worst case, 2 pair of vise-gipis.1 on the filter, and the other on the nut, as tightly as you can (to cause less damage to the nut in this case). Clamp down on them both and go for it. Iv'e had to do it with a brake line before (similer). Not professional, but it can get the job done.
Keep in mind. If the fuel line has a lot of rust, and seems like it has some deep 'pitting'. As in spots that look like are deep within the tube with rust. Then just say 'forget cost'. Replace it. Maby about USA $30 at an average if it's the tube going to the engine. If it's to the tank, it'll be less.
Let us know how it comes out though, and I'll check every afternoon to see how the information I gave helps, and any other help I can give on this.
