Re: [DML] Dwell meter readings + possible vacuum leak

["Mike Bosworth" <mike.bosworth@xxxxxxxxxxxxxx>]

Hi Jeremiah

I trust you are well.... just to clarify...

On the coal canister there are actually 3 hoses coming off.
1no goes to the cold start valve brass tube (canister purge line)
1no goes to the tank vent pipe
1no goes to the throttle body tapping.

Agree on the other blanked off tapping . My tapping is actually 
moulded in as part of the canister itself .. 

Kind Regards

Mike
