I have the M103 engine with the CIS-E. That just looks like a regular engine compression tester with a special fitting?

I'm interested in where to connect the tester. It seems as though you could separately test the pumps, the pressure regulator, accumulator, and fuel distributer by placing the pressure tester in different locations, each one possibly requiring a different 'T' style fitting, and each location would have an expected pressure. I'd LOVE to get an electronic one that changes resistance based on fuel pressure, then I could monitor the pressure while I test drive the car.

Thanks,
Robert
