Can anyone tell me if the device pictured on this 205 engine is the supplementary air device? The last 205 I owned didn't have any of this stuff, as a race car, and my Haynes is in another State. IIt's a long time since I laid hands on a standard 205.
The (presumably) air hose from it terminates on the underside of the throttle body, next to the distributor vacuum line - it can be seen enclosed in one of those corrugated sleeves. And yes, the hose clamp is missing a bolt.
The other air line which is connected to the T-piece is blanked off. Where does it usually go, and what, if any, will be the effect of blanking it off?
If this is, indeed, the S.A.D., where does it take its input air from? It appears not to be from the filtered inlet air, as I have removed all the trunking, and there seems to be nothing superfluous, and nothing missing.
