Conversion of ALDL to NMEA 2000

Wanting to read ALDL (1993 Chevy truck) and output to NMEA 2000 network so that my GPS/Fishfinder can read the data from the engine. Is this feasible with an Arduino? I have done a few projects with Arduino and am fairly confident I can read the ALDL, just not certain on how to convert it and output it onto the NMEA 2000 network.
