Definitely report back on that! I've had the same loud clicking for about 20k now (I've got 75k on my '13 ECO). It happens after the car warms up and I just chalked it up to overly noisy injectors. Hasn't hurt my mileage or anything, so I stopped worrying about it. If I can fix it for $20 I'm all over it!

Swapped mine out for a factory replacement this afternoon ($43 including tax) and the noise is gone. My old solenoid started making noise around 50k and I'll gladly pay $40 to keep it quiet. It was getting damned loud!
