If you learn how to post the picture, instead of the link to a picture you might get a faster response.

An AC line will never have a low pressure fitting on them. That I believe is your power steering return line. It leaves the rack, come over the motor mount, comes through the driver's side hose, the crossover line, than the passenger side hose. You should be able to get away with using regular transmission cooler hose, I don't really recall any special bend, however this is from memory and could very will be off. Good luck.

yeah that's the power steering cooler lines i believe as well. they are probably cracked and need replacing. get the dimensions and get a generic replacement from your local parts store. they carry generic hoses available at custom lengths. also get new hose clamps.

If anyone knows how much fluid might drop that would be awesome. I will buy a few bottles to have on hand and some kinda hose to route it out the front bumper if it does end up leaking a lot. Should be able to replace these without removing anything, lucky i have small hands

Depends how smart you go about it. If you do one side at a time and plug everything up as you work you shouldn't get much on the ground. I'm not sure how long those hoses are, but all the fluid in the old hoses will be gone.

very strange post..1st u have some mod going on under the hood,whatever that huge gray pipe is. so u must have some knowledge of cars? correct?
then u say some hoses are leaking? well whats leaking? what color is the fluid? or u can follow those lines to see where they go..i mean whoever is in the pic is already under the car and it wouldnt take much to turn his head and duck under to see it.
only an observation... just sayin man..not judging

Assuming they are power steering lines, make sure you use the right fluid. Check your owner's manual - it will also tell you the system capacity, which is your worst case for how much you'll need.

I don't know what year yours is, but for my '91 (and maybe all?), you don't use power steering fluid in the power steering. You use DEXRON III ATF. No need to use the $$$ Toyota Type T-4 in the PS.
