Odd Fuel Pump Noise

I have noticed lately that when I let my bike sit for more than two weeks the Fuel Pump gives off a high pitched squeal for about two seconds when I turn the key on. After that everything is normal until it sits for two weeks again. I think my Fuel Pump is giving me a warning? Anyone else ever experience this. The bike is a 2006 ST3 with 31K mile on it and runs great. I have owned it since new and have never heard this before.

I have an 07 ST3 and if mine isn't riden at least once a month it does the same thing. I think it's because the fuel drains out of the lines and the noise is the dry pump pressurizing. Now I'll turn the key on every so often so the pump doesn't drain dry. No noise since.
