What type of replacement hose for power steering?

[gshort24]

I sprung a big leak in a rubber braided hose going from my power steering reservoir to the power steering pump which has been relocated with my old GTM supercharger kit. The old push on and clamp down bulk hose is a Dayco TC4 which they don't make anymore. I did some research and it looks like a nitril/NBR type of rubber hose has very good resistance to ATF fluid. Does it really make a difference in durability if I use fuel hose vs a harder to find transmission cooler hose if they are both made out of NBR rubber? Modern fuel hose temperature ratings and PSI ratings exceed the specs of my old 15 year old hose, but I hear stories about not using fuel hose for power steering and its best to use transmission hose for durability. Not sure if that is still true in my case.

I’d use transmission hose to be safe since it’s thicker and should be more durable. You can get it on amazon from Evil Energy brand or go to your local Oreillys and they’ll have it.

Note that the hose you’re talking about is the return hose so it is NOT a high pressure hose and thus you don’t need an externally-braided hose.

I have a GTM supercharged car as well and have also had PS line issues, but I’ve resolved all of them. Send me a DM if you want to discuss more!
