This is the Alliant Power AP63422, a new fuel rail pressure sensor. It replaces Ford 8C3Z-9G756-A and 8C3Z-9G756-B and International 1873400C92.
Alliant’s sensor guide lists it for the 2008 to 2010 Ford F-Series 6.4L Power Stroke. The same guide lists it for the International MaxxForce 7, 2007 to 2016. Alliant’s page names the F-350, F-450 and F-550 Super Duty (2008 to 2010) and the International 3200 (2008 to 2011), 4300 and 4300LP (2008 to 2012).
Ford’s 6.4L water in fuel repair job aid lists the 9G756 fuel pressure sensor among the parts to replace, with the high-pressure pump and the fuel rails, when rust is found inside the pump. Alliant also shows this sensor as a related part on its 6.4L high-pressure pump.
