When you drop out the front pump you are cavitating the rear pump. thats the squealing you hear.
This is bad for it and dont do it too long.

Check the pins on your relays and try to expand them with a screw driver tip and make them fit tighter into the socket in the fuse panel. I am having the same issues with my relays. Though 6 amps to each fuel pump is not that bad....how hot are the relays getting when you run the pumps for awhile?
