What type of hose to use for pcv system.

Gates barricade fuel hose is what I like to sell people if it's something you never want to touch again. $4 a foot. It's ethanol resistant as well. I'm using some right now that was soaked in fuel and left in the sun, it's falling apart externally yet the inside is fine. It's probably 4 years old ATM. Still as stiff yet pliable as it is when it's new. I have a long piece for transferring fuel from things I'm going to let sit long enough to know the ethanol is going to die.
