Due to emission requirements, the number of vacuum lines and tubes is increasing. It is advisable when disconnecting tubes and
lines, to identify them in some manner so as to avoid confusion later. Trace the lines back from the carburetor to the individual
components, and identify that line. In the event that any components are unfamiliar, use a numbering system which corresponds to
each line and its original component.
