Thank you in advance.
It is fairly typical of most modern diesel stock fuel filters to be 10 micron at best (some other Japanese brands only have 15 microns). But I have spoken with a Jeep diesel mechanic here in Perth (Aztec 4x4) and he told me that all Jeep CRD's have 10 micron.
And again, most common rail diesel injectors are 5 micron. That's why all the aftermarket diesel filters only go down to 5 micron.
Anyhow for the most part, what I did was not done before, running a primary filter (stock) and a secondary filter (aftermarket) with the finest filter being 5 micron on a Jeep CRD, so I was just taking a gamble that it would all work especially as so many other people have done this to other brands of 4wd's as well.
This system has been installed for 40,000kms now and no probs whatsoever.
