FAQ: Racor Fuel/Water Separator

How can I tell whether there's water in my fuel? Just by looking at the plastic container at the bottom of the Racor fuel/water separator, I can't tell whether I'm looking at water or diesel fuel.

Drain a little fuel from the filter bowl into a small glass jar. If water is present, it'll bead up in the bottom of the glass. If more than a few drops appear, consider using a diesel water absorber. Keeping your tank full will discourage condensation, especially in the spring, fall and winter (Ron Hill).
