I bought the vacuum line kit for my 302 and I can not figure out how all the parts fit together and I can not seem to find it in the assembly manual. I have the long piece of hose and a short piece of hose, a metal line which I can tell fits into the carb and goes down to the intake. there is also a metal fastener that I can not figure out how it goes. Anyone have pics or can they tell me where to find it in the assembly manual?
