I finished my firewall forward wiring tonight and turned on the master switch for the first time. I expected to hear the fuel pump turn on but did not expect it to sound like a jackhammer! I pulled the fuse to shut it down so that I could begin to test the avionics so it was only on for a few seconds.
Is it normal for the pump to be so loud without fuel in the lines?
