You can get engine temperature onto NMEA-2000 with a temperature
sensor.
You can get
fuel tank level onto NMEA-2000 with a tank level
sensor.
You can get fuel flow rate onto NMEA-2000 with a flow sensor.
For a temperature sensor, you could use the Lowrance TEMPERATURE SENSOR (MSRP $99), see
Lowrance Temperature Sensor | Lowrance
For
fuel tank level, the simplest approach is to use a standard fuel tank level float sensor with a resistive ouput, then connect a Lowrance FLUID LEVEL SENSOR (MSRP $99) to the resistive output. See
Lowrance Fluid Level Sensor | Lowrance
For fuel flow rate you can use a Lowrance FUEL FLOW SENSOR (MSRP $199). See
Lowrance Marine Fuel Flow Sensor | Lowrance
Note that the Lowrance flow sensor only works with gasoline; it does NOT
work with
diesel.
There are other devices that require some
work on your part to integrate, calibrate, and wire up, as mentioned in prior replies. But the Lowrance sensors will be very simple to use. The only hitch may be the temperature sensor will need to be re-configured for engine temperature from
water temperature, and you would need a suitable Lowrance HDS display to perform the configuration; perhaps a dealer could do it for you.

The WEMA products seem like a good value in tank level sensors with
classic resistive output. See
