Howdy,
Out of interest I cut open 3 different manufacturers diesel fuel filters to see filter media. The filter fits an Toyota 2H and 12HT engine, and possibly others and is the Z169A model. This is Aussie based research.
I have no way of measuring the fineness - ie micron rating of any of the media, though Ryco have told me theirs is 15 micron. All were constructed with the filter media folded into pleats around a central steel mesh core, a heavy spring to hold the filter against the top plate and rubber gaskets to complete the internal sealing. All were the same height - 60mm, none of them were obviously the same or copies as is shown by the results.
Valvoline VF5
50 pleats with a total unrolled length of 1600mm
Cost around $12
Ryco Z169A
62 pleats with a total unrolled length of 2090mm
Cost around $14, or $10 in bulk
Donaldson P550057
82 pleats with a total unrolled length of 2170mm
Cost around $10 bought from a truck supplier, maybe Cummins in Bayswater WA.
I also cut open a Delphi 296 filter which goes into the common CAV adaptor or standalone auxiliary filter. It is of a different type of construction but has by far the greatest surface area of all the filter. It is 5000mm long and unfolded to 100mm wide. Cost upwards of $7.
I've cut open a number of the 296 filters before and there are clear differences in the length of the filter media, but don't have the results at hand.
What does it all mean?? The filter experts will have their say no doubt, but it tells me not all filters are the same and high capacity doesn't mean the highest cost. Not exactly a world shattering revelation is it!
