using closed loop would also be my first thought.. especially because it is possible .. and because "pump pressure modulation" is pretty sensitive to temperature and stuff.. open loop would cause bad precision..
Then I have an idea: Piezo Fuel line clamp!!

This is much cheaper than an expensive sensor, and the fuel line doesn't need to be cut.
I have 2 of these for 6mm lines and I already tested it on my mTDI . It gives a 2 Volt pulse between the " body" and the " fuel line" .. that 2V are pretty good measurable with an oscilloscope, and for sure with a DSL1 it will be measurable too
I made two pictures to explain my idea about testing and measurement:
Step one:
- make modified fuel lines and measure the line pressures in a running car with full load and high boost and high rpm.
I think 3 fuel lines are okay .. the sensors are not cheap either, but I need more than one, to be sure..
The sensors can be calibratet first, to be sure...

Step two:
- Make some kind of check valves that will induce the same pressure in the lines as the life running motor ... and then drive the pump with an electric motor and a measurement shaft.
Via the pressure sensor, the functioning of the check valves can be verified. Via the measurement shaft, the pump load will become visible.

After that, the choice of the phaser will beginn...
