Fellow RV'ers,
I had a bit scare today: as I was taking off, got low fuel pressure warning and low fuel flow. I turned the electric fuel pump on (have a dedicated switch for that, and normally I keep it on during take off), and everything went back to normal. A few minutes later in flight, while on slow climb, I test again by turning electric pump off, and same thing happened (Rotax 912ULS engine is less than 50 hours) so kept it on and got back to home base (KJYO). Just before touch down, to test it again, turned off electric pump off, this time didn't get the warning. Taxied normally back to parking (with pump off) and did a final high RPM check, still everything seemed normal.
Less significant issue (on the same flight):
Just had my Dynon Skyview Touch serviced and put it back in the airplane and ran setup configured it. Everything worked fine and including autopilot. Set a direct flight plan and wanted to navigate using Autopilot, Roll -> Nav mode. However, NAV mode was not selectable, only HDG and TRK was selectable. Any thoughts?
Any thoughts what happened? Mechanical fuel pump failing or any other theory? I am new owner, so still got lots to learn.
Thank you for your valuable comments.

Monir
