Message	Any ideas why my fuel pump buzzes so loud? The buzzing correlates with the throttle and fuel pressure. 12% throttle has me at about 2.5 bar fuel pressure and the pump operates quietly. At about 14% throttle the buzzing begins and the fuel pressure spikes to about 3.5 bar. And this is pretty loud(and annoying). Loud enough to still hear it with the radio on about half way up. My setup is an NA converted to TT. Swapped fuel pump and controller. Fuel pressure is being read by a Greddy gauge with the sensor mounted directly after the fuel filter. Throttle % is read by my SAFC. This same motor and setup did not act like this in my previous Z. Thanks guys and gals.
