tranny lines, auto, 86
Ok, dispite my best efforts , and spraying the line with WD-40 and Buster, I still twisted the bottom line going into the radiator. Is this a high pressure line and can I use a short length of rubber hose for the repair..yes, I went ahead and broke it, it was useless the way it was. thanks.

People use rubber hose to hook up trans coolers all the time. EFI rubber hose is rated higher psi FYI and I'd suggest using a high psi line since trans can be pretty high at times. Many people use push-lock or braided soft line for the whole length but it's rated for pretty high psi.
Look at your local auto parts store for brass compression fittings, then use the length of steel line you need. They might even have the small line cutter that works well in tight spots if you need one.
I bought some pre-bent SS lines for my C3 from a corvette site after failing to get the zig-zag around the frame right with steel line, but that was before I knew about Nicopp line that bends easy.

I'm with "Boot77" and I'd replace with NiCopp as the prefered BUT if you insisted on a flexible line I'd use a 5/16 INV FLR (1/2-20) push-on in the cooler and create a short flare on the existing steel line to create a retaining ridge for the hose and clamp well. The shorter the coupled length of flexible I'd think the better. Did you twist it off close to the nut?
It would certainly do for a temporary fix to get driveable.

If you use rubber hose, use ATF cooler hose. Any decent parts store will have it. ATF will eat into fuel line and make it soft and easy to slip off.
