Getting loud liquid/water sound in the center dash when the car is cold. Seems to recall someone had mentioned that it is the fuel pump. Opinions? TIA.

Default One possibly symptom is your 02 voltages (AFR) leaning out significantly near redline.

you'll also hear it (from the back of the car) - a higher (or changing tone) pitch buzzz
