I replaced the vacuum hoses coming off of the SC Bypass Actuator. This is the one between the Bypass Actuator and the Bypass Solenoid, and I also replaced the one from the Bypass Actuator to the top of the engine where the brake booster hose is also connected. The brake booster hose is fine and the rest seem to be holding up well. I just did it at Advance Auto Parts with a vacuum hose line I happened to have for patching washerfluid hose. Was the right fit. I just figured if someone knew the rest of the diam & lengths I could order new red silicone ones for the entire engine.
