Update!
I rebuilt my old oil cooler hoses from the lines I had. Here's a little rundown:
I picked up two of these caps at Lowes. They're half-inch, but I'm not sure what the threading is. They fit, though. I just used them to plug the filter housing in case the oil decided to try finding it's way out while I figured out how to fix my old hoses.
Then I used a dremmel to carefully remove the crimps from the hoses. I made two cuts along the length of the crimp and stopped a little short of where the crimp meets the line. Then I just pried it back and forth until that part popped off.
Then I just attached some 300psi hydraulic hose from the hose and fitting place here in town using two hose clamps at each end.
Now I'll just have to keep it close to town and watch it for a few days. I still haven't sent the other ones back to Amazon. I meant to take a picture to show you guys just how much longer it was. Anyway, I feel pretty good about the new lines, but I'll update if I notice any leaks.
Mg84648, sorry for hijacking your thread, and thanks for bearing with me while I beat myself over the head with this thing. That goes for you too, cucvrus.
