Hello all. A friend of mine has a tierra 2 ultra light tail dragger 532 rotax. Twin carb, dual egt, electric fuel pump running parallel with a bulb type hand pump. (Is this for emergencies? Incase the electric pump goes in the air?). So the dash is totally torn apart wires all over the place. I am very confident in my wiring abilities I have wired boats race cars trailers even brand new fire trucks. I also worked for mack trucks in macungie working on electrical issues. I know these connections are crucial so I plan on replacing some of the wiring and fixing what I can. (Things like bad terminal). I will solder and heat shrink. So here are a few things I really need help with
Why two fuel systems?
Why two egt probes? The turbo cars/ diesel trucks i work on only have one
Why no lighting on this thing? (Sorry if stupid question this has no strobe no green/red not even any instrument or idiot lights or power lights (to show ignition is on and fuel pump is on this is really common in the race car world figured it would be in the flying world as well)

What should the egt be at idle 50% and wot?

This electric fuel pump is running with just a switch, we always put them on relays. Should i put this on a relay? Or is it more parts to fail?

Any general advice would be appreciated. Or any quirks with the 532 or the tierra two would really be appreciated.

Sorry for soo many questions. Just want this to be perfect.
