what size fitting do I need for the cp3 to run a 1/2" line on a 01/02 LB7 pump? looking for something similar to the fittings that come with an airdog system and not sure what size it is thanks

You talking about the supply line fitting? It is a 12mm x 1.5 pitch.

yes supply line fitting. I want to get the adapter to put a 1/2" fitting on it to run the pushlock hose thanks.
