I am looking for the check valve for my 1978 GMC Royale 403 engine
California coach. I got a new Mondello 403 engine and unfortunately the
check valve coming from the Vacuum control Valve got lost.

Does anybody know where I can get this check valve with part number etc.? I
appreciate any help. Thank you.

I am not sure what you mean by a "Vacuum control Valve".

Are you referring to the heater/air conditioner controls?

Or, are you referring to the check valve that is in your brake booster?
