Fuel Filter nut stuck. replace fuel line?

I am about to give up on this bolt. Soaked PB Blaster over night, my friend and i, with steel bars for leverage, still couldnt break loose this nut. Seems as though the fuel filter must have enver been changed on this vehicle. It's a 1994 Pontiac Grand Prix SE 3.1L V6 with 132k miles.
Actually, we pretty much smashed the nut so even if we got it loose, we would have to replace it.

I was wondering, is replacing the whole fuel line from the filter to the engine (or closest fitting towards the engine) a practicle option?
Anyone ever do this?
It is steel tubing...would i have to bend every turn?
i know the tubing would be cheep, but any ideas on the price of tools and fittings required for the job?

...the car doesnt run, otherwise i wouldve taken it to a shop to have them attempt to replace the fuel filter themselves.

sounds like replacing the line is now the only option.
the line is inexpensive, and no, you would not have to make all the custom bends to follow the frame (just make sure you tie wrap and/or bolt up the line, as you don't want it dragging down the highway;
sparks+fuel=BAD) and chassis.
the lines will probably be about $3-7 depending on 16"-4' lengths, the tubing cutter about $2-3, and you can get a bender if you like, but if you have the old line out as a kind of template, you can pretty much 'pre-bend' your new line on the shop bench with wooden blocks, or in the vise (making, minute 15-30degree bends at a time).

One thing you can look at is to have a shop cut the line a bit down from the filter, use a flaring tool on the end of the cut line after a new fitting is slipped on and get a new piece put in the gap bewteen the new fitting and the new filter. Just an idea to keep costs down. If you have a friend with a flaring tool, you should be able to do it yourself.

the fuel lines are an o-ring style, not an inverted flare on these cars, and they make a repair kit that comes with a compresion union and a 12" piece of line. They run about $10-$12 at most auto parts stores. Also, make sure you clean the rust off the old line so the compression union can seal.

would you happen to know the name of this kit? because that sounds perfect.
thanks a lot!
