Note to anyone replacing their fuel filter; there's a nut on the top of the filter. You can hold the fitting on the lower fuel line and spin the filter itself [remove the top fuel line and loosen the filter clamp first]. This helps to prevent damaging the fuel line.
You can tighten this way too.
If it's really bad you can cut off the bracket for the fuel line off the top and use an impact and socket.
You should definitely be able to do this.
It's very important to get the flare right or it will leak; that's a very easy flare to do.
Do yourself a favor and buy a good flaring tool like that. Cheap ones are a pain.
Also, make sure you cut the line STRAIGHT. If you cut it crooked it may not flare right. A compact tubing cutter is probably best.
Make sure you clean the cut end of the tubing after you cut it.
You might need a section of tubing, depending how far from the current flare the kink is.
You're also going to need an adapter to the fuel filter [AN to metric]. I can't remember what size thread the filter is.
Do yourself a favor and buy good quality fittings like russel or earls.
IIRC the TOP fuel line [fuel rail to pressure line] is equivalent to 6 AN, so that's what I'd start with for the bottom.
But double check.

Good luck!
*With all that info in mind, I completely forgot the lower filter is a flare fitting also. You're going to need an adapter that has a metric flare end to match the flare end in the filter. I'm not sure if that exists.
You can also use a different filter that has a compatible lower fitting, but then you'll have to adapt to the upper fuel line. This might be the easiest option; the upper adapter just has to be whatever the filter is to a metric banjo.
Or you can do a metric flare on the bottom. This is a more complicated flare [it's a double flare] but definitely can be done. If the kink is up near the top this will be much easier [you're cutting the kink out and reflaring lower down [don't forget to put the nut on the line before you flare it.
I hope that covers everything.
