Fuel Pump Pulsator
I was reading about how these can stop fuel pressure loss and vibration, but how does it work?
Also, does my car have one?
I looked in the Helms index and did not see it listed.

these is one of the item the FSM states will cause a decrease in fuel pressure after the pump turns off.
