hmm, definitely a tricky one to locate the right p/n. Just to be clear, it isn't the sensor for when I am low on fuel, I am needing the low fuel pressure sensor on the fuel line. My understanding is there are two fuel pressure sensors, one on the fuel line near the brake master cyl, and another on the fuel rail. Fuel rail is high pressure sensor, the other is the low pressure sensor. Effectively it is stumbling and dying at low rpm occasionally and everything is pointing to this low pressure sensor but the exact PN for the non-ecoboost version doesn't always show the same number depending on where I look. Is this the correct one you are referring to?
