The Multi-Fuel Monitor, formerly known as alcohol monitors, are spin-on dispenser filters offered by Cim-Tek Filtration that detect BOTH phase-separation in ethanol blends AND detect water contamination in neat gasoline. They utilize state-of-the-art microglass media. The Multi-Fuel Monitors are UL Recognized for ethanol-blended gasoline up to E15 and neat gasoline. The ultra-sensitive super absorbent polymer forms a gel when it comes in contact with water, thus reducing the flow drastically. This indicates that there is a problem in your tank: either Phase Separation if it's an ethanol blend or water if it's straight gasoline.
