What are you guys using for breather hose? I'm looking for 19mm/.75" hose for my 20vt breather system, but everything I am finding says "heater Hose", and I know what happens when you use rubber heater hose as breather line. Now all the hoses I have been looking at are silicone, but didn't know if it would hold up.

Thanks for any advice.
