Diesel fuel and corrosion

Last year I placed some bottles in the shed, one vented, one with a silca gel filter. The exposure was only 10 days at this point.



This year I repeated the test, adding corrosion coupons (not examined yet). This has been exposed since December.



Seems pretty reproducible. The condensation only takes place in early spring, when it's damp enough during the day and cold enough at night.

Also curiously, while silica gel seems to work for multiple seasons on e-10 gasoline tanks, it seems to last only a few months on diesel; while gel worked fine in the first test (10 days) it failed in the second (3 months, image not posted). I need to do some confirmation testing on that, and we have filters in the field.

What does this mean from a practical perspective? Puzzle it through. I'm certain the answer depends on the boat and the usage.
