Hi Andrew; The acidic water may have encouraged rust. I have tried hot water and found it to be an improvement so I don't think that is it. I am no chemist but I understand that water is a polar molecule and oil is non polar so they normally don't like to hang out together but if there is something like a soap which has one end that likes water and the other end that likes oil it works something like a religious official who can join a man and a woman ( which also naturally don't like each other) and you have a problem ( in both cases of course) called an emulsion. Funny I never realized it before. God help me if I ever feel like getting emulsified again! There must have been something else in the water or fuel. It could be something small. Sometimes a small drop of surfactant for instance in a large amount of water can change it's property dramatically. How reliable is your water supply?
