There are two variants with these filters. The local SA ones are the Chinese manufactured ones with a mesh of 0.1mm. There are American (possibly the original) that is less prone to blockage I understand. All I know is, many many people have had problems with these filters. In my case the blockage was almost invisible and after just 5 hours of cleaning. This is not anecdotal, it is real and they are dangerous. Period.

What are you saving? R80 every 25 to 50 hours? and how can you be sure you have cleaned the microfilter sufficiently. Is it worth it to take the risk?

By the way it only needs to block the very bottom few milimeters near the threaded section to stop all flow completely. So don't be fooled at the large surface area the filter appears to have. The image below shows how much was actually blocked. What you cannot see, is the threaded section inside the filter, that holds the two parts together, The sharp edges and tiny cleareances ensure a 100% blockage with very little dirt.

I moved the Optifuel wiring question into another thread because it is a different subject

Can you have a look on the filter and see if it states the country of mfg. :?:
As mentioned previously we have no problem with them in Oz on 582 and 912.
We had a Europa flying around Oz last year that almost had a problem but this was due to dirty fuel from drums.
Fortunately he had a glass filter and could see the dirt (^^)
The merc diesel filters are translucent so you can also see dirt in them. I recently replaced a filter after I saw some debris had collected in the low spot. Turns out I have paint flaking in my jerry cans. :!:
