Depends on the technology also. Many engines now use a single fuel supply line with no return, as I recall with a variable-speed fuel pump. One benefit is that the fuel temperature in the tank doesn't fluctuate up and down as much, causing condensation, promoting algae growth, and then leading to unhappiness. However, you're right, older diesels return the fuel.
I'm still a big fan of using a hall effect sensor to note a sprocket wheel / water pump / etc. rotating nearby. Pretty straightforward to implement, non-contact, and very accurate.
