Hello,
From the beginning I have had a problem with a fluctuating fuel pressure indication on my Dynon EMS120. It seems to be something with the indication, the fuel pump is fine. Since I have had a warning from the Dynon announcing "low fuel pressure" (which was not an actual low pressure), I thought I better get this issue fixed.
I investigated and found out that Dynon no longer sells the old style "one wire" pressure sensors, but now supply a new type (Kavlico) sensor that has an additional earth wire. Not a big deal, easy to run an additional earth wire from some place convenient FWF. But.... now that I have received the sensor, I find out that it also requires a +5V agitation supply. I do not have +5V FWF so I would have to run a new wire from behind the firewall (Dynon), it would be not so easy to find that wire in the Dynon wirebundle (all nicely tugged away) and more important I would have to penetrate the firewall .
Does anybody have a suggestion how I could avoid to have to penetrate the firewall with a new wire? Can I get +5V from an other source?
Thanks in advance for the advice.
Regards, Tonny.
