It needs to be the correct approved part or it will fail. If the guy comes back I hope he posts a picture of what he needs. I think he is looking for the pulsed air injection tube.

Yeah, he said it goes to the back of the air cleaner which makes me think it's the air injection? If it's the simple heat riser duct that looks like a dryer hose but much smaller, that's $5 at the auto parts store. That one goes from the heat shield on the manifold to the thermostat on the air cleaner gooseneck on the front of the cleaner. But the pulse air injection tube and the valve is a little more complicated and tougher to find. I stupidly gave my PAIR to some guy who took it because his was missing too and he never donated to the site as promised. Now I'm out a hard to find part. Otherwise I would've given it to the OP. LOL

The first gen uses a flapper valve you can get from Napa auto. The metal pipe might be harder to find.

The metal pipe might be harder to find.

I think you might be able to bend up and flare your own but judging by the length and odd turns in the pipe, it's tuned for scavenging. So I guess you could potentially screw up the air intake with you got the length wrong. But the approx. 1" diameter pipe might be too big to bend and flare without special tools. Or maybe a thin wall conduit pipe packed with sand and heated with a torch with some threaded fittings on the end?
