condensation water in fuel tank
follow up to a previous post that one or two people might be interested in.
a 120 L ss fuel tank was left 1/3 to 1/2 empty for 2 months in area with relatively high humidity and typ 10-15 deg C difference between daytime high and nighttime low temps.
for a differnt reason (i had a suspicion of some contaminated fuel), i had the fuel "polished" (recirculated at 40 lpm for 30 minutes = 1200 L recirculated volume through separators and filters) while moving (vacuuming) the intake hose to the "polisher" via the inspection hatch to all parts of the tank, especially the dependent (low) parts.
interestingly, there was no, zero, 0 water in the separators.
