1986 300SDL WVO oil filter

Has anyone developed a way to predict that your FM100 (or other WVO filter) is getting clogged? i have found that i don't have much warning when it is starting to affect the performance of my car. If i didn't have the option of switching to my second tank (diesel fuel) it might really get in trouble some time on a longer trip.
Is there a way to do it with a pressure gauge prior to the filter.....?

Interested in you comments.

Strange sound at 1800 RPM while accelerating in 91 350SD

I just changed both fuel filters and the oil on my 350SD and on my test drive the car made a strange noise or vibration at 1800 rpm. It almost seems like a cavitation. Motor mounts are good....I did a diesel purge 3000 miles ago....and it's normal and smooth at all other speeds. It has a newer non-rod bending 603. New nozzles needed??
