Fuel filter ratings for the 6.5 OEM FFM? Newer plastic top design?

    Anyone have info on the filters currently available for the stock 6.5 OEM canister? Specifically Micron ratings and Water Separation ratings?

    I ask in the long ago context of the stock of metal top filters being replaced with the plastic top style. Looks like the original filter manufacturer for our 6.5's was sold off, quit making them, sent overseas, or whatever. Strange with all the military 6.5's out there. (Sure the aftermarket filter setups can mop the floor with the stock design, but, I am not asking about aftermarket.)

    I read that the NAPA Gold is 5 micron but not confirmed....

    Wix 33976 micron Absolute 14 micron

    WIX Filters - 33376 Absolute 14 micron

    Baldwin BF1201 - Nominal 3 Micron Absolute 9 Micron

    ACDelco TP1256 I could find no specifications for ACDelco filters - ACDelco sucks - zero customer service

    If anybody has time they could contact Hastings and a couple of other filter companies and verify their specs.

    Understand How To Use Micron Ratings.
    A micron is a unit of measure in the metric system equal to 1 millionth of a meter in length (about 39 millionths of an inch). The average
    cross-section of a human hair is 50 microns. The human eye cannot see anything smaller than 40 microns in size.
    50 microns – Diameter of a human hair
    40 microns – Lower limit of visibility of a human eye
    25 microns – White blood cells
    8 microns – Red blood cells
    2 microns – Bacteria
    A micron rating is used to indicate the ability of a liquid filter to remove contaminants
    by the size of the particles. It is important to remember that a micron rating without an
    associated beta ratio or efficiency does not fully describe the performance of a filter.
    A filter that has a rating of “10 micron” has some ability to capture particles as small as 10
    microns; however, because there is no single accepted way to measure and describe the
    size and amount of contaminants a filter can hold, you need more information. For a micron rating to be truly useful, you must know the
    filters’ removal efficiency of the specific particle size in question.
    There are several variations of micron ratings, but the two most common terms used are nominal and absolute.
    Nominal Micron Rating
    – expresses the ability of the filter to capture particles of a specified size at an efficiency between
    50% and 90%. For instance, a nominal rating of 50% at 10 micron simply means that filter captures 50% of contaminants 10
    micron in size. Keep in mind that nominal micron ratings may range anywhere from 50 – 98.6% efficient at removing a specific
    particle size.
    Absolute Micron Rating
    – means that the filter is capable of removing at least 98.7% of a specific size particle. This rating is
    determined through a single-pass or multi-pass test in which fluid containing measureable particles is passed through a flat
    sheet of filter material. Particles that pass through are measured and counted. This rating is more informative than the nominal
    micron rating.
    When you call the Baldwin Catalog Hotline with a question about a filter’s micron rating, you will be given both the nominal and the
    absolute micron ratings. Typically the nominal rating is a 50% efficiency rating. However, this should be verified if not given to you.
    If you are ever provided a micron rating by another filter manufacturer, it is important to ask if it is the nominal or absolute rating, as
    well as the percent of efficiency rating and contaminant capacity. This will allow you to better assess the performance of the filters
    being compared.
