The fitting to the motor isn't the problem. They used some weird size hose (metric?) that isn't quite 3/16". I visited a number of parts stores last week, and no one had a standard compression sleeve and nut that was a direct match for the existing hose.
Stephen in Reno indicated that the hose/fitting is part of the SPF install kit. He was supposed to ship me the part today. Thought this was going to be a quick fix.
