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??

1987 300 sdl - odd starting problem

i am having odd start up/running syptoms. car starts and runs perfect when cold. after warm up, requires 2-3 starting attempts. intermittently will not take fuel after warm start (especially if i continue cranking on first attempt until firing - usually no more than 10 seconds). fuel filters have been changed, diesel purge performed (actually looked pretty clean). car has 241,000 miles and looks to have been pretty well maintained. timing chain is tight.
