Indication of fuel pump issue?

[Wheels]

I am currently installing a Dynon DS10. the manual discusses the fuel sensors Dynon is using, and establishes some software update criteria. I'm not ready to join this discussion but ... did you install and update all the new stuff?
I also watched the video and have to say that sometimes, we have too many gauges. "a minor fluctuation can steal your bliss over nothing" or it can indicate that your about to test ALL of your skill. I didn't see anything that scared me, but I don't really count as I sit here on this computer and you fly that little ship into the sea of air that we call ... sky.

Alex- do you have a fuel regulator? When my fuel pressure started fluctuating like that it was my regulator, and the mechanical gauge didn't pick it up but my digital did- FWIW

Thank you for all suggestions. I did absolutely nothing and today's flight I didn't notice any variation.

I am guessing here I had a little air on the fuel line or perhaps a bit vapor that could cause this. It was hot that day and vapor could possibly be the reason.

Will see if happens again. Hopefully not.
