I've seen the ghetto-bleed for the lines (pressurize the line, then have someone try to bleed pressure at the schroeder valve). Fire risk tho, so be careful.
I am curious about the voltage too, as the tuner that I was using was running through the fuel pump line at my truck harness and had never made the noise before. Probably not the smartest move, but I'm impatient from time to time lol. But the tuner has been uninstalled as I said. I will check the voltage...

I can handle bleeding it that way. I can do that without the truck running, correct?
