So, I was changing my fuel filter (spring tune). After I was done, I wanted to check for leaks so I turned the key forward to the Auxilary position, which activates the fuel pump. With a half a tank, noticed it was making a loud "garggling" noise. It seemed louder than I've heard before. I can never hear the same noise with the exhaust
Is that normal? I suspect it'* about to go.
