Interesting! Maybe I can control that pump with a durametric, it's possible with the 997 (MK1). Will report back!

Yeah, I’m not convinced it’s a pump, the noise pitch changes and pops sometimes as well regardless of if the engine is on.
Check out the noise changes in response to my pumping the pedal:

I’m thinking it might be somehow related to a worn light switch assembly that may need to be replaced or poor stereo grounding or radio interference
