moran75 Posted January 2, 2020 Share Posted January 2, 2020 (edited) Hi all  hear me out on this one🥴  my heat/air system has never worked properly, but that’s ok - I can live without either...not a priority ...currently researching , will get around to it one day..  BUT what I have done is break off the vacuum nipple at the heat door diaphragm...so I now def have a vacuum leak..  This got me thinking....I potentially already have other leaks elsewhere in system...  As I’m in no rush to repair everything , but want to avoid performance issues no matter how small or inaudible to untrained ear, how about plugging the ‘main’ vacuum hose from the T at back of carb...therefore isolating the whole heat/AC system ?!  Thanks in advance  kev   Edited January 4, 2020 by moran75 (see edit history) Link to comment Share on other sites More sharing options...
