I am guessing you have 2.0l D (here is no 1.9 AFAIK) and so an mzr-cd (rf turbo) engine (same engines appear on the Mazda 6 and Mazda 3 so you can use those fora too)
try here (somewhere)

This was my goldmine; this seems to be unlisted (web indexing excluded) and there is no contents page (if you find one, post it here please), higher level directories are error 404, no breadcrumb trail. But basically ALL the Mazda 5 maintance steps that are red-crossed out and missing from the 5 workshop manual version that is all over the internet (i.e. the steps specific to the mzr-cd (rf turbo) diesel engine) are on that Mazda internal site-somewhere. Just jump around between the links, you'll find it.
Also the official Mazda work arounds (with shorting wires etc) for OILDIL resets, inj. calibr. DPF force regen, etc. are also all there!
There is something on that fuel filter in this mazda6 forum:

and somewhere here (also good for general stuff) falls Sie Deutsch verstehen / uebersezten koennen:

fill the tank full before. Open the tank cap/opener before starting the job to relieve neg. pressure on the line (and leave it loose unitl after you have tested the filter change/fuel flow). Use golf tees etc to stop up & cap fuel lines. Fill the filter to overflowing with diesel before replacing. Hand pump it until the pressure exceeds the strength in your fingers (these are tips for any modern diesel).
For me my 5 started right up after 2 sec. If not, and trying to start for several seconds, the damage to your car is not the starter and battery use (this is nothing) but dry air going into high pressure pump and then the injectors;
