KSL-B-14, EPX-3-09 | Filter Element

(14 customer reviews)


The filter is the first line of defense for the heater’s intake. Unusually dirty fuel will “age” the fuel filter more rapidly than clean fuel. It is recommended that you replace the fuel filter, as well as the o-ring, before each heating season for best performance.
