don't use copper unless you like walking! most copper tubing available to teh general public is a certain type and it will work harden and fatigue. there are special copper tubing that will not do this but they are pricey and hard to find. also note that copper should not be used for brakes or fuel for the same reason and it is actually illegal in most states to do so. do not use rubber the entire length as it is weaker, retains heat, and breaks down. buy premade sections of bendable steel line from the local auto parts store. 5/16 is the minimum you really want to use but 3/8 won't hurt but gets necked down at the fittings (but the larger line aids in cooling). hawkrod

I would be interested in Stainless braided lines if I could find them. Did you use your original fittings on this hose? Any suggestions?
Also, in another forum I was told the lines needed at least 140 pound pressure rating. Do you know the pressure rating on your hose?
Thanks....

Zach, I merely cut out the "mid" section of the factory steel line and retained the factory fittings (with say 1-2" worth of nipple) into and out of the radiator and tranny. I fastened the braided line to the fittings using regular old stainless hose clamps. You can find braided lines at most speed shops or at Jegs or Summit Racing.
I don't think you have to worry about the pressure rating on braided lines. I think it is much higher than 140 psi, but I don't believe there is nearly that much pressure running through cooler lines anyway.

I used the rubber tranny hose for both runs (I was in a hurry) This is some thick tuff stuff- I used double clamps on the ends and wire tied it up real good. So far so good, but I would like to make some good metal ones soon- Man that hose was spendy- like 3 to 4 bucks a foot- Should have done it right the first time
