Larger filters, higher (smaller) micron ratings, far better water separators....Yes, You defined 'extensive' well.
As a crude estimate.
Take the size of the water / fuel separation bowl in total volume.
At 75% power (not uncommon in towing or Class 8 truck operation at highway speeds). estimate GROSS (not NET) fuel needs for engine operation.
Based on engine GROSS fuel needs in volume per minute (note that excess fuel is needed because it is recirculated back to tank for cooling of FI components, etc.):
Estimate how many minutes of operation will it take to fill the separator to the WIF sensor level with water if 100% water was pumped from the bottom of the fuel tank to the fuel water separator that is filled initially with diesel only.
Then estimate lag time for WIF to light (roughly water level high enough to trigger sensor, plus a bit of lag time).
Next, estimate the time left to shut down engine / switch to alternate fuel tank from WIF lighting to water entering the fuel lines and making its way to the Fuel injection system.
This kind of a safety margin estimate is much more accurate than just looking at how big the fuel water separator is.
What you will find is the safety margin is not that many minutes.
