ABSTRACT:
A spin on fuel water separator having a filter element attached within an electrically grounded housing, means are provided for supplying an electrical potential to the filter element and the filter element is electrically insulated from the housing. Separated water is stored within the housing, and when separated water accumulates within the housing so as to contact the filter element, a current flow through the filter element, the reservoir and the housing is indicated. The housing includes a reservoir bowl provided with a warming coil which allows separated sludge and water to be warmed prior to removal from the device. An optional embodiment includes a means for detecting and indicating a restricted filter element.
