Where can I get those? I have a 1995 T/A if it matters. Can I just use any old rubber hose? I bought a salvage yard engine and they cut both the rubber lines coming out of it. What is each one for...both are vents??

 

One line supplies filtered air from the intake elbow to the Opti, the other pulls a vacuum, by connecting the Opti to t port on the driver's side of the intake manifold. The harness includes a filter and a back-flow valve.

Shoebox has photos of the vent connections, and part #'s on his website:

This site also has the part #:

If you already have a 95, you should already have all the hoses on the engine.

 

Someone stole a bunch of stuff from my car when it was down...including the opti and intake elbow. I might still have the one going to the intake but I think it was still on the opti.
