DIY: brake/fuel lines

Recently discovered that i am leaking brake fluid from my lines running underneath the driver side. I took it in to get it checked out and was told that not only do my brake lines need to be replaced but so do my fuel lines because of how corroded they are. I was qouted 1000$ plus and to be honest i cant afford that at this point in my life so i absolutely need to do this myself with my brother so i can save money. Anyone who has exp with this? Degree of diffuculty? What parts i need? Where to get the parts? I really love my gtp and would hate to get rid of it.
 


Honestly not bad.

Head to your parts store and pick up a bag of the bulk fittings for the brake lines. IIRC they are on the PA labeled premade lines, that way you can find the sizing. Then figure out what the fuel lines need to be as well. Except realize you can't put a union (legally AFAIK) in a fuel line. So you'll need a way to get around that (I'd go braided at the end ..see the how to braided line thread). I strongly recommend the NiCopp or Connifer line. It's much easier to bend than the steel stuff. It also should never rust out again, the steel only has a coating on the outside. it's more expensive, and so much nicer.

Buy a decent flare/double flare tool. I got mine at Sears, it's about a $50-$65 craftsman and it works great every time.

Then watch a couple youtube vids on flaring and double flaring.

Jack up the car and you'll have a few hours under there.
 
It is not hard at all to make nice lines and flare ends, the key is to be patient and take your time making the bends and the double flares, don't buy a cheap flare tool either, you don't need the most expensive either, just get a qulity dauble flare tool and practice first. SOme lines under the GP neeed to be two pieces to make it much easier to install, just use a union to join them, it save alot of time and aggrivation than trying to snake one long line into place. I had to do this on the rear brake lines of my GTP.
