I was just under the hood installing a new pcv valve, and I think it's time to start working through all the hoses. I'll probably get all OEM for the molded hoses, but does anyone have a good source for bulk metric vacuum hose, and an idea of diameters needed for the 100? I hear silicone is the best, but I'd go with whatever Toyota used because it's lasted 20 years.
