my vacuum hose that connects to my plenum is so worn out that when the vehicle is running the hose closes on itself almost completely. It is the 90į joint which is a couple inches long that is worn out, the inside looks even worse. I was wondering where and what i could buy to replace (i aleady tried 2 ford dealerships and they said that piece has been discontinued )
-I don't want to buy something that ends up breaking down and shooting debris in my engine.
-Also, it is strong enough to stay open when the vehicle is on and the vacuum is running.
