ELEC. FUEL PUMP NOISE

Rubber isolate the mounting plate from the frame, and the pump from the mounting plate.
Also, gerotor pumps (like a big block oil pump) are usually quieter than vane pumps, which your blue is.
And agree, the Carter will be quieter than the blue, and probably last longer.
Edit :isolation mounts are probably available from mcmaster-carr or grainger...... or you could use a piece of old inner tube, lol.
