as mentioned it can be messy. make sure first you have the proper power steering fluid....
then you should probably buy the hose from a dealer, or PM "Toyotapartsman" here on these boards with ALL information he will need.
or just go to your dealer.
parts stores "may have" these parts for a toyota, maybe not. prices will be very close to dealer.
you will need jack stands
proper wrenches like "flared wrenches" which grip the fittings better than open end wrenches.
they typically look like this, where you would ned a 3/8 inch drive socket wrench and extension

you then put a drip pan under the area, and remove the bad hose
install new hose
refill with the PROPER power steering fluid...
now, you will need to "bleed the system", and here is where you need those jack stands. jack up the car, place the jack stands under the front control arms, so the suspension does not hang.
start up the car, and make several FULL left then right turns....(stop to stop)..DO NOT hold the wheel at the end of the turn, just do this several times, like maybe 10 would be good. shut off car, lower car, refill the power steering reservoir if it needs it......
done....
it is messy, and time consuming because you NEED to do this right....otherwise, you will have a bigger leak, or get air trapped in the system which takes TIME to bleed out, if NOT DONE correctly the first time...
