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
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.

For advice on modern implementations of resistive fuel tank level senders, see
The WEMA products seem like a good value in tank level sensors with classic
resistive output. See
