The fuel pressure running the mechanical pump varies between 22 and 26 psi in a 1 second interval. Is this normal or a bad relief valve ? Looks pretty nervous.
When switching the E pump on the reading is very stable 28 psi.
I purchased the 10 a year ago and it was like this all the time.
Another problem is occasional short pressure drops to zero only when flying 5000 ft and higher. Pressure return immediately but the Garmin lady starts shouting.
This happens 2-3 times an hours and makes me nervous.
The relation to altitude makes me suspect the sensor.
Any thoughts?
