So I get a new pilot assembly out of my truck, i remove the pilot tubing from the old one and put it on the new one Make sure the little orifice does not fall out of the new pilot assembly. and make sure the pilot tubing compression nut is tight. It is easer to do this with the pilot assembly off the burner and with out the thermocouple in place. after it is tight it is time to install the new thermocouple.
