To me it's not worth replacing lines unless they are leaking, as that requires an evac (pull vacuum), before you recharge because you've now opened it up to atmosphere. Besides if it's just surface rust you can make it look better with scotch bright / sand paper and metal polish. We have a place here locally that will make a/c lines for about $25-30 called hosefast, but since I'm guessing you don't that's definitely a reasonable deal for some oem ones. Good luck.

Also while you have the lines apart it would be a good time to replace the A/C compressor with a newer R134A one.

Would I find a R134A on a late model Cherokee @ a JY?

 

And I wouldn't be surprised if there was a rust hole in the line somewhere... Its pretty bad looking.

You don't need a new compressor to switch to R134a, you just need a conversion kit, and while youre replacing lines, replace the receiver/dryer too, especially if youre converting. When all is said and done with your parts, youll need to have it evacuated for at least an hour. This will remove all traces of old oil and refrigerant before adding the new stuff. This is a requirement, not an option if you want to do this right. If youre handy at all, replace all your parts, and then take it to a shop that can evac and recharge it for you and add the needed amount of the correct oil for the system. Then youll be happy all summer!

Yup, no need for a new compressor. Mines converted. No advantage to R134, EXCEPT that you can actually buy it... Some will even argue that R12 is colder but is getting exceedingly hard to get a hold of. Especially if you don't have a license. So I'd definitely recommend the conversion... it won't cost you much but time and will save you money in the long run, for sure.
