I'd be interested to see what you find. Before I rigged in my
filter as a pour spout for the 6 gal cans, I used to consistently find a
very small amount of gunk and water in it. I'm assuming you're using the
water-absorbing type filter element?

It's not the greatest picture, but you can see the filter I'm using he

BTW, since this pic was taken I've re-routed the plumbing so that the filter
now sets upright, perpendicular to the fuel tank. This allows water to
settle to the bottom of the filter, and be drained out of a petcock valve at
the bottom of the filter.

Never found any yet.
