What’s the problem with the 90s?Swapped in the new Optical Sensor and was successful in fixing the diesel fuel leak that was coming out around the snap ring and out the connector.
Scored the old encoding sensor on both sides of the clamping plate before removing the T40 clamping screw.

Gauged the distance to the score from the edge of the encoding sensor with a micrometer / caliper and, as it appeared to the eye, the clamping plate was perfectly centered on the encoding sensor. Scribed lines on the new sensor with the micrometer and reinstalled the encoder.
Put the pump cover and everything back together along with PMD Ground and the return line. Jumped the lift pump for a few minutes to purge the air and it fired right up. Skipped a beat once or twice finalizing the air purge but the motor just continued to pure away. No diesel coming out the retainer ring or connector either so, THAT problem solved.
In order to monitor OS for a while I reinstalled upper intake set up I prefer with the Peninsular 'hat' and elbow from a Cummins. Since the lower intake wasn't tapped for Boost or Air Intake Temp. sensors, I pulled the old Spacer Ring I designed years ago out of its hiding spot and put it back on too. Just the way I want it.

Yeah, yeah, 'too many 90* bends'.... Whatever.
