Slightly embarrassed, cannot for the life of me figure out where this sensor goes. Did a bunch of maintenance and thought I took plenty of pictures during disassembly, but I don't know where this guy mounts. It's the pressure sensor that has a rubber hose about 4"long that attaches to the intake manifold right next to the injector. It seems to want to land somewhere near the bend in the tube frame, but there's nothing there. Service manual didn't have any info that I could find.
