This may sound like an odd question. I have another avionics systems that are connected to my fuel flow transducer as well as my fuel tank capacitor probes. Question, am I able to parallel the wiring from the existing locations into the skyview EMS with out degradation of either system?

If they are a 4-20 ma loop that should not be a problem. It needs to be hooked up in series not parallel.

Not sure how to connect serially because there are only inputs, no outputs to the nondynon equipment. I can split the inputs but not able to pass the signal through the units and out to the dynon.

Without knowing what your capacitance probes are we can't say. Even if you do parallel things, you get no redundancy since the failure of one instrument is likely to take out the other one.

You also can't parallel fuel flow senders without knowing details of the hardware inside each instrument.

OK thank you. Since the NMEA 232 will not TX to the EI FL-5L I was entertaining paralleling the signal so I can take advantage of the fuel at destination and fuel to destination.  Not wishing to remove what I have because it is integrated into other systems.
