[Vwdiesel] Do I have a "yellow dot" pump?

[David Cook]

Here is the VW part number off my pump:
068 130 107 A

I think someone told me that it was a "yellow dot"
pump, which is earlier than the '81 engine, right? 
(Well, I was told the engine came out of an '81
Rabbit, who knows, maybe it had been swapped in that
car?)

Is there a site with info to decode the pump part
numbers?

What should I time that pump to?

Finally, where would the alleged yellow dot be on the
pump? 

Thanks,

David
