I hear it come on, but I can also lightly feel it in the seat when it turns on. I do not think the fuel pump is the source of my noise. It's coming from the passenger side of the engine bay and only during accel. Considering the vacuum leak. I'm sure these cars have pcv systems? If so does it have a saip? I know the saip cuts off after warm up but the noise seems to cease when the car is at normal operating tempeture. I don't know, could be a lot of things.
