So might have been an air leak.
On the RPM issue, instrument died, so until we replace it, I'll just thank you for the advice.
Haha , thanks for the update, I guess after 3 years it’s been well and truly solved. Happy boating.

Update on dying issue - I checked and the guy said the pump was simply dirty inside.
Otherwise, all was top notch. He replaced o-rings, just in case (since it was open already).
There is racor pre-filter installed so seems a bit strange.
Luckily, it was just that ....
Still worknig on RPM issue. Seems I'll have to replace the instrument. We tested with another instrument and all works.
