Am currently sorting my vacuum system. A vacuum gauge (Amazon) is proving very illuminating and my problem quickly traced to the dash switch and /or the fit of the short connectors to the main pipes.

I've gone a bit left field (added some weight.. Sorry Chunky) and installed a vacuum pump & pressure switch. Seems to work fine and so have now blanked the inlet manifold but it could be run in conjunction with the manifold port like a lot of moderns do for brake servo
easy to return to standard if needs be & they go up & down just as sedately as before.
Hope will also make the fuelling a bit more consistent.
