Super interesting. Thank you for that.
Do you have part numbers for any of the thinner hoses coming off the turbo or ACSD? I can try to work with those and find you what you need.
Following.
I tried to find Toyota bulk hose part numbers awhile back. I don't think Toyota sells bulk hose, but I could be mistaken.
I ended up buying the longest Toyota hose I could find and just cutting it to length.
