1977-78 PD carb float bowl vent.
You will notice in this photo from the net that the fuel line going
into the carb is very poorly routed.

My 77 with PD's doesn't have vent nipples, or at least I can't find the damn things. Maybe I'm blind but I can seem to find them, I was trying to track down a wet weather stumble. Interesting to know some weren't equipped with them.

The vent hose is right next to the fuel line filling up the float bowls.
If front of it actually.

Here you go Lucky, I had my tank off tonight and my PD41A's do not have vent tube nipples. Where the set of PD's off a 78 motor I have do have them.
