Does the M1008 have a second fuel filter???

Hello all, I have an 85' M1008 and been doing some reading and watching videos. In a couple of them they talk about the 6.2 having 2 fuel filters. One block filter/water separator for large particles and a screw on filter at the back of the intake for smaller particles. I looked and the mounting holes are there, but my truck has no second filter. The block filter outlet goes straight to the DB2.

Is is it supposed to have this second filter?

No.

The CUCVs only have the single filter.

I think 82-83 trucks (not CUCVs) had 2 filters.

Does anyone know what micron the block filter is? Most injection pumps and injectors need at least 10 micron.
