    thanks for finding the image.
    I have noticed the last couple of times that i have been changing filters exactly this issue also - more so on my BIO filter than the WVO filters (both are CAV filters) - i had never thought about it before but will definitely be changing this around on the weekend

    That paint thing is pretty annoying eh? Have you ever come across another brand of filter that isn't painted? I assume the filters aren't the same on both ends, so flipping the filter upside down won't work?

    It certainly looks a funny way of doing things.
    This page explains how it works with diagrams

    These Wix brand elements seem be paint-free

    They are a different animal altogether. They might physically fit, (I haven't measured so not sure) but they work quit differently. Note the photo where it shows a solid bottom to the filter. The 'tube' up the centre is where the fuel exits the filter (quite like the sketches shown earlier in this thread). My filters of which there are several connotations have s solid lining to the centre and a perforated base to which coalesced water (read glycerin) can drain from. If they physically fit they might work just fine, but I would still run the fuel through the wrong way as all the crap (glyc, dreaded white stuff etc) would accumulate at the top of the filter. Ok so paint isn't a problem but they will last longer and you get a true indication of what's going on with your filters. I used to wait for the 'feel' of a clogged filter. Now I just check the bowl and clean as required. I might get 3 or 5 cleans Before changing the filter.

    Yes, If you go to the page I linked to it shows the fuel flows from top to bottom of the filter with V joins in the pleats to remove the crud as it flows from top to bottom.

    Tilly,

    That was a very comprehensive run down on filtration systems. Love your work.
