Greetings all.
1981 CX500C. There are two small hoses on the vacuum petcock. I understand one is for the vacuum hose routed to the right intake manifold and one is a breather tube that hangs down by the swing arm but... which hose goes to which fitting on the petcock?
My idea is the vacuum hose goes at the far end of the petcock to pull the diaphragm open and the vent hose goes in the middle of the body but if I apply a vacuum to either fitting on the petcock it will flow fuel. Remove the vacuum and the fuel flow stops like it should.
Looked online and in my Haynes manual without any luck.
Next question is, has anyone swapped out the vacuum petcock for a non vacuum operated one? I really don't see any use for one.
Thanks all.
