Compensation Tube

Like Roger said, I mounted my MAP sensor at a high point, used the small orifice to dampen pulses, and did one other important thing (I think):

I mounted a small brass tee in the sensor line, at its lowest point. The 3rd leg of the tee is pointing down with a plug in it. Every annual, I remove the plug and drain any collected fuel. It never drains more than a drop, but at least I know it will be dry.
