I have some metal lines for power steering on an old tractor that were bent and now leaking. What is the best way to repair this without replacing the whole metal line?

With the rubber lines right there anyway, Cut back to good straight metal. Put on a flare fitting if your equipped, or a compression fitting if not.
(Doing either RIGHT is the most important part. PS runs around 1000psi rough guess)

Select fittings to get everything to hook back together. I'm saying less than $60 in parts, you might wnt a new hose assembly depending on many things. Oh, and make up a support bracket that keeps those lines out of the way ;-0

Agreed, go flexible to hard with better placement and geometry.

I have used compression fitting to fix PS issues like that a few times. A 10$ tubing bender from Harbor freight, 6 feet off steel line and 4 compression fittings will be less than 40$. The cheap flaring tools from HF are not worth it.

Remember, you can get legit compression connectors for real hyd applications.. Ie, good for anything 1 or 2 wire is good for... Not just low pressure Hyds.

Clean up the spot where it leaks, and braze it...

Replace the metal lines with hydraulic hose.

EAs stated, attach the flex hose to a good portion of the hard line and fabricate a proper bracket.

On the fittings go with proper hydraulic ones as stated. They will cost more.

If I was doing it, and wanted to keep it looking original I would get some new tube, bend it using a tube bender, and cut the old line flare it, and replace the bottom 90 or s bend on the lines using the JIC fitting like on the tractor all ready,

for fast and dirty fix take out the torch and braze them up, and keep on going,

the last way would be to get some longer hoses, and cut off the bent metal reflare and use longer rubber lines,

some depends on skil and tools, but if tool short take the lines off and take to a shop that has the tools and have them reflare and bend the parts,

looks like at least one of the lines is nearly bent in half.. that's a bad flow restriction... needs to be cut out.
