After several engine runs, I've noticed a brownish film has appeared on the surface of the hose. The hose is rated to 250 F but I'm wondering if this is the wrong hose type for this application. What is the proper hose to use in the engine compartment for the vacuum hose. I have the same problem with the MIL-H-6000 hose for the oil breather lines.
