    The stock Yamaha configuration for your bike is one fuel line, from the petcock to the carbs (the big fitting;) and one vacuum line, from the vacuum spigot on the #3 intake manifold to the small port on the petcock.

    The other three vacuum ports on the intake manifolds remain capped except for when you vacuum sync the carbs.

    Take a look through the petcock rebuild article; even if your petcock is fine there's a lot of other valuable info in here: http://xjbikes.com/Forums/viewtopic/t=25058.html

    you get some little OEM caps w/clamps from XJ4Ever; or you go to the nearest auto parts store with an existing cap in hand and match it. And use a tight zip-tie as a temporary clamp until you get some real ones.
