What type of petcock do I need?

[cmills83]

I have a '77 reproduction tank, '80 engine/carbs. I see there is a manual petcock available but also a vacuum type petcock which I think was used on the '80, I'm a little confused on what the difference is and what exactly I need.

You will need what fits the 77 tank. I believe that is manual petcocks. 80 engine/carb will probably have vacum ports that will need to be capped.
