SOUNDS LIKE THERE IS SOMETHING LOOSE UNDER THE IP / DASH IN THE INTERIOR COMPARTMENT. I TRACED THE SOUND TO THE FUEL LINES, WHERE THEY ARE MOUNTED TO THE INTAKE MANIFOLD. THE HARD LINES ENTER THE REAR OF THE CSFI UNIT AND THE BUZZING EMANATES FROM THIS POINT. THE VIBRATION CAN BE FELT IN THE ACCELERATOR PEDAL AS WELL. THE NOISE IS WORST ON A COLD ENGINE AND / OR WHEN THE OUTSIDE TEMPERATURE IS BELOW 80-DEGREES OR SO. THE NOISE IS ALWAYS THERE ON START-UP AND ON NON-HOT DAYS, IS CONSTANT. A FEW TIMES THE NOISE IS NOT HEARD AT FIRST, BUT AFTER 30 SECONDS OR SO OF OPERATION THE NOISE RETURNS. AGAIN, THE NOISE IS PRESENT AT ALL RPM, ALL DRIVING / RUNNING CONDITIONS. IT'S ALMOST LIKE A GURGLING SOUND IN THE INTERIOR COMPARTMENT, MAKES ONE BELIEVE THERE IS SOMETHING DANGLING UNDER THE DASH BOARD OR THERE IS AIR IN THE COOLING SYSTEM /
