    Anyone ever notice there is a fuel filter in the injector delivery tube on the QSC? Item 16 in the attached is listed as part number 4903218.

    Wonder what size the filter is in mics? And wonder if they should ever be changed?

    Phil,

    I personally have not, but I am sure I have 2 techs that have.. I’ll look into this..

    I would guess that this would be the equivalent of the “edge filter” that are used in most all of the regular injectors found in the mechanical B & C engines, only engineered differently for these injectors..
