On my 74B, 72 18V engine, the gulp valve has a large hose running from the
carbon cannister, a hose to the bottom of the car and a small, approx 3/16"
male end that is not connected up. Is this a vacum connection?
Also I do not have a crankcase breather tube. I just installed a Weber DGV
and there is a fitting under the air cleaner that I understood connected up to
the crankcase breather. I have not had the car running since I have had it,
but very close. do I need a crankcase breather? All openings are sealed off,
apparently the engine ran this way.
