Hey guys, my vacuum check valve just broke on me the other day and before I realized it the valve had fallen and part of it melted. So, if you could I have a diagram of the vacuum line could anyone please tell me the part number for number 4 on the diagram?

 

I would get them from ecs.. more than double the price at the dealer

order a few.. they all break in due time
