thanks

There was a hose connection on some SCs
Tony was looking for the keeper recently
Bruce

Hose connection for the carbon canister.

I figured it was a hose connection :-)

but no idea what it served (purpose), obviously its not in use on my SC engine..i had guessed maybe it had to do with a temperature switch of some kind since it was open to the external top side of the engine? Nothing a breather would require...just run out of ideas what it could be

HELP!

Gomer

Really...wow, thats wasnt on my guess list..so whats underneath that tube, ie what does it connects to?

thanks!

You connect that nipple with a hose that fits and run it to the carbon canister nipple. It moves air through the canister.

There's positive air pressure inside the cowl that the cooling fan creates. That pressure purges the CC from gas fumes.

found this and now it makes sense

Here is the key:
1. Expansion chamber
2. Vent chamber
3. Charcoal canister
4. Engine fan shroud (under air cleaner)
5. Hose from fan to charcoal canister
6. Purge line from charcoal canister to air cleaner

so it would make sense to cap this off so hot air isnt blowing into the engine bay?

It's not there on a 85 it's in the engine compartment Attached to the package shelf.

mines an 83 so checking now in the pet, but do i cap or just leave open?

I would hook it up.

hook it up to what, there is no remaining Carbon Canister?

I just plugged mine with a small piece of the hose and a screw and two hose clamps

778..put a cap over it and forget it..no need to have it.Or send it to Tony as Bruce said he was looking for one;-)))
Ivan

Which Tony? If i can get it off easily I will...

well , you would have to remove the alternator and pull the little lip tube in plus the sunshine clip is a PITA to remove..Just cover it wit a plug.Tony is a 911 engine master ,CIS and WUR ..engine rebuild class is one of his threads...boyt911sc..

Ivan

Ahhhhhh...i dont think i will go that far, i just capped it off and will use some red touch up paint to "clean" it up. Sorry Tony

thanks everyone..PP forums are great!
