'81 FC air leak

[davidkerryedwards]

Yep, it's the vacuum generator. You've been messing with the cruise control
haven't you!!
If there's a leak in the cruise control system, it will cause the generator to
bleed off. It also
could be bad vacuum generator. They are NO LONGER AVAILABLE. Plug the main
line
coming out of generator and see if the leak stops. If it does, there's a leak
somewhere up
in the cruise control system.
