I've been running a gauge for monitoring the internal lift pressure for some time now.
It's been a valuable tool for early warning signs and diagnosing various issues.
The gauge gives an audible "buzz sound" at times so I'm wondering if anyone else has such an item
and if they're getting similar sounds. Looking carefully, the needle isnt totally steady when the
buzzing occurs. Lately I've been taking more notice and I see the symptoms at the lightest of throttle and disappearing when the throttle is opened.
I reason that there could be tiny pulses in the lift pressure, possibly the harmonics of the high pressure end of the IP reverberating.
One thought is that the gauge is a cheap item and sound is from the small workings inside.
I think these have like a miniature rack&pinion setup which could easily account for the chatter.
I understand an oil filled guage is often used in industrial situations to overcome frequency pulsing so
that could be a fix?
Google some time ago turned up someone puzzling over the same phenomena.
