T&T: Racor 500 filter cartridges

[Peter Bennett]

The previous owner of my boat used a Purolator PF3148 cartridge in the
Racor 500 filter.  Does anyone know the micron rating of that
cartridge?  I do intend to change to genuine Racor cartridges, but
would like to know what rating filters have been used.  The spare
filters on board are Hastings 848 (2 micron) and Wix 33208 (10
micron).

Also the on-engine filter has been a Kralinator F152 or Fram 4102 -
any idea of the ratings for these?

The engine is a Cummins 6BTA 250 HP.

Thanks
