This reminds me, I can hear my pump noise/wine change pitch …or audible level in sync with my blinker on. It’s done this for some time, never had it be an issue, though I wonder if I'm lacking some voltage to the pump at idle? If so, maybe I’m not getting the best fuel delivery I could be, this is just some random thoughts I have. Any thoughts?

That's exactly what it is. the stock wiring is inadequate. Voltage at the pump has a huge effect on pump speed. As long as you have enough fuel at the rail it doesn't matter though. The wideband tells all.

If you do the rewire mod it will quit.
I even noticed a difference in sound when it primes from just doing the rewire.

Messing with electrics isn't my stronger point, but if its simple and I can find some clear directions on how to do it, I'd be interested in doing this mod.
