Power steering line replacements
 

I am swapping out my leaking rack and while I'm in here I plan to replace the power steering cooling lines. Thankfully the high pressure lines going to the rack are in good shape.
It doesn't appear that the cooling lines are high pressure and could be replaced with standard 3/8" line (that was actually a listing on one site - a box of 3/8" cut-to-fit). Figured I would confirm that understanding here with people that actually own these cars.
She is an 86.5 7MGE so no fancy PPS or turbo components.

I have replaced my power steering return lines on a 7MGTE with 3/8" oil resistant transmission hose. The reservoir hose(s) may be a different story, since I don't have a fender mounted plastic reservoir. 3/8" is slightly smaller than the metric size Toyota used so apply a little transmission fluid to slide it over.
