Hello to everyone.
I have a very erratic oil pressure gauge reading in the cockpit.
Installed a connector T at the oil pressure port on my 2100 D and
attached a direct reading gauge for verification. Direct reading gauge
is very steady oil pressure while cockpit
instrumentation is sporadic fluctuating from 0 to 40. my question,
assuming I need to replace the sending unit, does a sending unit have
to match the happi gauge or can I buy an off the shelf sending unit?
Cheers TIA

Keith,
Not seeing a response I'll throw in my non-mechanic opinion. Buy an off
the shelf gauge and see if it matches the direct reading test gauge. I
can't imagine that it wouldn't. My only concern is that any gauge used
have a very tiny orifice in line in case of a leak in the gauge it
doesn't dump all your oil before you can get down safely.
