Danger, Danger,
what you have is plain old.. H2o,
the tank you have is it insulated?, if not then you will always have a moisture content that is really only seeable once the juice is oldish, the tank should have one of those big fuel filters after your pump, that will take out most of the moisture and slowly expand so as to stop you pumping anything with a high moisture content in it , then you are forced to change the thing, and clean out your tank.
I have refurbed a lot of trailer Bowsers and find they all suffer from moisture if they are not insulated, in fact I picked up a 320gall tank one day to be told its half full and we cant pump anything out!, reason Filter totally blocked by swelling due to moisture, so contents pumped out and into a new couple of barrels to see what its was,... oh it was half full alrightl , but made up of roughly 120 galls of water with about 50 gals of Avgas,, possibly the mans Jet R could have had some new sort of H2o burning turb..
Any uninsulated tank will make a suprising amount of moisture, even though the lid may never be opend for long, its pure physics, fuel gets warm in daytime, tank gets cold at night, your fuel then starts to float on the unseen peril of the sky.
Insulate or Die, or scrap your Bowser and get a new one, insulated and fully bunded so as to be within the new rules!
