Probably overkill, but I put braided stainless lines in to replace the failing steel transmission cooler lines (92).
I had a Parker Hannifin shop crimp the ends on.
I removed the lines from the truck and had the lines cut to match approximate lengths. Did not replace rubber lines to aux cooler with braided stainless.
Hose used was Parker Braided Stainless Steel 919 Teflon with 91N series fittings. Fitting Numbers are parker-hannifin numbers (as near as I can decipher from the hand written bill, been a while since I did hydraulic plumbing). Inches are hose lengths before end crimped.
Not the cheapest of upgrades (about $200 USD) but will not need to be done again. Been in for about 5K miles, no probs so far.
And as a bonus, this should make plumbing an aux filter in easier (when I get around to it).
HTH,
