Alert me when someone posts in this thread:

That hose is discontinued. If your a diy dude or dudette you can make one. Yes you can damage your motor because the purpose of that hose is to pull vacuum out of the valve cover keeping you from blowing valve cover gaskets.

The hose your talking about actually has a metal hose molded to it and the metal hose inside the vacuum hose needs to be salvaged out of your busted vacuum hose. Many have a theory as to why Saab mounted a metal hose inside the vacuum hose and you can believe any one you want but personally I think its to keep the large vacuum hose from fully decompressing if it was ever possible in its brand new hose state.

The metal hose runs to the throttle body then to the pump. Pull that hose out of the large vacuum hose and install it without its vacuum hose companion.

The valve cover vacuum hose other end is installed into the plastic turbo duct work it's just pushed into that rubber grommet. Wiggiling while pulling on it will free it.

Head to the auto part store and get 5 feet of heater hose. Take the valve cover nipple to get the right diameter hose. (One that fits the nipple) then get a hose clamp that fits the heater hose. Now head to Home Depot or lows and find a long spring that fits inside the heater hose snugly (this will keep the hose from decompressing) then head to the plumbing section and find a small one inch pipe to fit into one end of the heater hose.

With the hose clamp mount the pipe to the heater hose push in the spring connect one end to the valve cover nipple and push the 1 inch pipe heater hose end into the turbo duct works rubber grommet.

Done and done
