I use a baha when filling via jerry can, which is typically in the wintertime when we sail less so that I can keep our fuel tank
topped off for our hydronic heater. After 5 winters, my routine is to grab a paper towel (actually 2 of the mini select a size ones) and a plastic sandwich bag before refueling.
I empty the jerry can into the fuel deck
fill using the baha filter, and when I get to the last little bit I pick the baha filter straight up, ball up one of the paper towels and put it against the discharge end to catch any remaining drops. Then I dump the contents of the filter into the sandwich baggie. Make sure you open the baggie first before picking up the filter. I do a sort of "clear and bright" visual on the baggie contents to see if there are any particulates or any freestanding water. If it looks good, I pour the contents into the diesel tank. If there are any issues, I throw the paper towel that was on the end of the baha filter into the bag with the diesel. I then use the second paper towel to do a quick wipe of the filter (but not screen) and put that in the baggie too. If the fuel was good, the baggie acts as a seal against diesel fumes and I throw it in our garbage. If the fuel was bad, the paper towels soak up the fuel and minimize the chance for leaks
until it can be disposed of, and I keep it topside to ensure there are no odor
