Thermocouple for older teledyne laars pool heater

I’m looking for a thermocouple for a Teledyne laars EPC-400 pool heater.  It has a  two wire connection from the thermocouple not thef tube units that I am seeing.  What is the proper manf # for the thermocouple with the wires?

We’d be glad to assist you. Does your thermocouple look like the one below? If so, the replacement is part number 6203-061.
