So just to give a little advice on how to do this job, if your line is rusted out, I 100% recommend using a hacksaw to chop out the old line so that you can use a 6 point socket on them. (Don't use a 12 point socket!) After removal, it was incredibly easy to put the line in over the fuel tank, if you have a friend who will lay under the truck and guide the line through, you can put the line through in under 5 minutes. Lining up the fitting on the ABS block is a bit of a pain, I recommend re-bending it by hand, you're going to need a tiny line wrench to get in there, it took 10 minutes just to tighten it down because there's only about 3" of room in there.
The fitting above the axle is a 15mm, however at the ABS block it's a 9/16, most videos say 15mm but a 9/16 fit it perfectly and didn't strip the fitting.
I'll take some pictures of the newly installed line when the rain breaks here.
