Those hose is a insulator, metal tubing has the ability to disipate heat. There are problems that could happen with a hose like inner shell/liner could deteriate and fold over blocking flow from the inside, I doubt this would happen with ATF but I've seen it happen with other oils. Surely Mike has some more reasons also.

In my experience the more exposed hose you have on a pressure line the more chance something can happen. Rub through, heat insulation as you mentioned, heat from the outside touching the hose. I use hose only as a last resort. I would keep the hose as short as possible.

Nice work on the hoses Im sure they will work great for you:)


A little FYI-you do not need teflon tape here. Teflon tape is only required on connections where the threads are the sealing surface. Pipe thread is an example of this type of fitting.

Flare, AN and JIC use the tapered surface as a sealing point-the teflon tape doesn't come near this surface!


X2 it appears that you used it on the A/N part?

If so you will now need to use tape or paste to get it to seal if you ever break them apart again.

I myself prefer a crimped on fittting....Simply cheaper and seem to hold better than pushlock

also is some one wanted to keep the metal it wouldnt be hard to bend up some tubing



Again nice to know that you saved money and did it yourself:thumb:

Mike, would adding a clamp on an engine bolt somewhere help, sort of like how GM used to do it with metal lines?

Funny, when the oil cooler lines failed on my 6.5 they didn't fail at the oft maligned crimp connections like everyone else in the world. They split under that damn clamp in the middle of the hard line. :confused:

I put OEM replacements back in and wrapped the bejeezus out of the line under those clamps before installing...

X2 while heavy equipment isn't the same they use as much hard lines as possible. Thats not to say they don't fail too.

As long as the clamps stay tight, steel line should last longer than hose. I like hose cause it is easier to deal with though and it takes alot longer to rub through a good hyd line as opposed to a thin wall steel line. But that's just my opinion-in the end, it all will fail!!

I just found the oil spot for the second time. The bad news is I'm no longer under warranty and I don't want to pay my dealer to replace them. I have some know how, not a pro, but enough. Will I be getting over my with this? The directions on making the new was are great. Just wondering if you simply just cut the old lines off, and adjust the length of the new ones. Do you have to drain any oil or does just a little leak out?

It's very simple to do just need some tubing tools to cut and flare the metal lines. Drain the fluid in a clean pan so you can re-use afterwards.

Okay thank you, I think I will give it a try. I've got those tools so I should be good to go. How do you pull the tubing off of the transmission and radiator? Does that take a special tool to do that?

No special tools. There is a black plastic cover that you must remove and slide down the tube, you can see them in the pics. Then there is a small metal clip that you pop off w/ a small screwdriver or knife be careful not to lose it or bend it when removing after that the tube pulls straight out. Its connected like this at the transmission and the radiator.
