What do you think about this washable fuel filter for FC (JDM)?
EPMAN support told me it has a 80 micron stainless stell mesh that can be renewed with ultrasonic bath or similar cleaning methods.
Isn't the 80 micron mesh too large for avoid crap into RX7 injectors?
If it is good enough it will be a good stuff because it will be a lifetime fuel filter.
Thank you

Correct, 80 micron mesh is too large to prevent particles from reaching the injectors.
Bosch (also supplies Injector Dynamics their cores) actually recommends 5 micron filters and says that anything over 35 microns will cause damage.
Personally, I use aeromotive filters. While the filter elements aren't reusable like the epman product you attached, they're easily replaceable and come in a 10 micron version.
Remember that any failure in your fuel system has the possibility of blowing the engine. A little investment in protecting this system goes a long way.

What is the micron rating of the stock OEM Mazda RX7 fuel filter?
Do you know other fuel filters with the reusable steel mesh that are rated low on microns for JDM sport cars?

All things considered, I'd say your best bet would be to use an OEM fuel filter.
They are cheap and have a long service life.

FYI, this reference article up on the ID website recommends filtration at 5 microns or less: Fuel System Filtration : Injector Dynamics Support

IMO, i doubt these aftermarket filters perform better than OEM. almost all "performance" filters sacrifice filtration for volume. while i have personally tested the stock filter to flow enough volume still to support upwards of 500whp on pump fuel.
why i think that? because i've personally seen plenty of stock injectors with upwards of 150k miles that still had less than 5% variation in flow. while that isn't totally definitive, it does at least speak something of stock filtration.
if you have lots of junk in your tank, nothing is going to keep it out of every corner of the fuel system unless you start with the part that matters, the fuel tank.
if you do wind up with some super filter, chances are it could become clogged much easier, resulting in fuel starvation and potential engine damage from lack of flow to all injectors. the ID writeup is a result of people building cars that started with poorly maintained fuel systems in the first place. if your fuel tank has ANY rust in it at all then it needs to be addressed first and foremost, especially if using higher levels of ethanol which will strip it off and send it through the system much quicker.
