Having problems with the fuel pressure sensor and indication with the RV12iS and Dynon system: The fuel pressure reading with pump 1 running is 39 psi and with both it's 41 psi. A direct reading at the fuel line leading to the right fuel rail is 46 &48. Have swapped out the Kavlico fuel pressure senders, removed the gasket keeping dust out of the electrical connector (don't know what that was supposed to do) and changed the fuel sensor input mapping from direct read to differential reading all without any changes.
The Rotax performs well and doesn't seem to mind the low pressure reading in the cockpit - either take off or cruise.
I would really like to fly without having a "RED" light indicating a problem and being put in a position of having to decide whether there really is a fuel pressure problem. I've heard that the Rotax engines don't work to well without gas. There should not be a warning light on in the cockpit and ignoring it can breed complacency with other warnings
Any ideas will be helpful.
