Fuel Management Flow Sensor / Sender Help

[ginmills]

I am trying to fabricate a complete fuel mgmt system starting with just one of the new Speedometer / Fuel Management combo gauges [6Y5-83500-40-BK]. I need the proper harness and sensors, and have an 89 Excel 225 and will be buying a T8 kicker.

My homework has shown that the fuel flow sensors have evolved and I want to make sure and buy the best with proper compatibility. So far I've found:

a) 90891-40351-00 aka 6Y5-85752-01-00
b) 6Y5-85752-02-00

What is the difference between these? Also, can I pretend I have twins and put flow sensors on the 225 and the kicker feed lines to manage total consumption?

On the harness I've found 6Y5-83553-F1-00. Do you need just one harness for both sensors back to the gauge? Thanks in advance.

You can order 6Y5-W0088-70-00 single eng Speedo/FMM kit and it comes with combo gauge, wire harness and sender.

Thanks, but already have the brand new Speedo/FMM gauge. So what sender and harness come with the kit you specified?
