Fuel rail pressure sensor

[oneton]

Ok, I'm in the process of changing out my Fuel rail pressure sensor. Bought a factory Bosch replacement but the design is different. The original had a provision for the washer/gasket to sit on the end where the new one is missing this. My question is, does the new sensor require the gasket as the original?

on edit: been thinking about this and wondering if what I am seeing on the original is the "crush" thru the center of the washer/gasket. Thoughts?

Thanks
David
