Edm 960
just an update:
for now I think I have decided not replace my senders (which in the SM on the C&D model are referred to as transmitters). But for those with a C or D, we have a unique arrangement on fuel quantity it seems (per the manuals). On our models we have three items of note: - we have a single gauge gauge per engine, even though there are 2 tanks per engine...to determine fuel quantity on aux we hit the microswitch overhead(automatically pushed when you switch selector to aux) - we have 2 sep tanks per side (later models went to a single tank I understand) - we have resistive 'transmitters' n each tank to send fuel levels, later models went to senders and the 'penny cap' system now on to the EDM-960...the T337C is on the STC AML, which is good. they even have specific notes in the regular installation manual that refer to inline thrust twins (yay, we're a real airplane). it seems that you mount the DAU (per engine control unit) on the cold side of each firewall, and then run a single wire to the display head....that will eliminate a lot of wiring to the back engine. it also seems I will be able to get rid of the plumbing from front gauges to back engine around MP/RPM/FF/Oil temp/press by reusing my EDM-760 probes, and a new harness, I am hoping to save a reasonable amount of time on the install...also trying to combine with annual, so plane will already be all opened up. will try to post pics once it is all in place (and the progress pics). JoeP & KristieS at JPI (yep, JoeP is the JP part of JPI) were great at the booth, saying they would make sure I had what I needed, including replacing any of my current probes if needed, new harnesses, etc. Last edited by rmorris : 08-11-17 at 02:13 PM.

The "Transmitters" are resistive type sensors for the fuel tanks. Always thought the JPI or EI full tilt display would be really nice but for the time and money I can think of a lot more panel items I would want instead. The original steam gauges and indicators are livable in my scheme of panel upgrades. That JPI is really cool though

3 tanks per side
Well I'll be darned...Herb, you must really know your plane
 Dug through IPC, and see the attached pics...sure enough, there are two tanks each side that are plumbed together to make up the main tank...so guessing there really are 3 sensors per side....weird design. anyway, thanks for sharing your expertise !
