What is this pipe outlet for ?

[Qldelsie]

Am fitting my engine today, and I realised there is an outlet at the front end of the right hand heat exhanger which seems to have no use. I remember now that when I took the engine apart, this pipe just had a (perished) rubber cap on it and was sealed off. There is no such outlet on the left hand side heat exchanger.
But I am intrigued as to what it is for. Is this in fact a heat exchanger off another model VW ? A bus ? A Beetle ? Or is this a real original Type 3 heat exchanger and they all have this unused outlet ?

Additionally I notice that one of the straps holding the insulation in place, although they both seem to be original, does not seem to be located in the groove in the metal protective cover plate that was seemingly made for it.

Anyone able to shed any light on this item ?

Thanks

It is for the warm air to the air cleaner to prevent carb icing. Mine does not have that.

Yup, carb pre-heat hose fitting. Uses some of that 1 inch flex hose up to the air cleaner adapter box (mixer box) with the summer/winter controls on it. Most of the later heat exchangers don't have it (at least in the USA), due to having FI.

Plug it again if you aren't using it.

Aha - Yes. Gotya !! I wondered what went onto that outlet from the air filter box ! I will get some hose and join them - Not that I need it in tropical Queensland, but might in Alaska !!!
Thanks all for input - Another problem solved.

Just took the doors over to an "expert VW man" this morning, so hopefully that will be done in the next few days. Now I am off to do the wiring with an auto electrician. Inserted a 30 amp fuse in the line between the battery and the regulator yesterday, so that was another job done. Tick.

Do you mean this upright pipe with the 2 bolt blanking plate on top, Bobnotch ?
If so, here is a pic of it while I was dismantling the engine,

After your reminder last night, I checked the engine today, now it is in the car, and you can see it is still in place - A bit shinier and cleaner now than it was !!

I hope this is the one you meant ?
