MDR Water Probe Indicator for Gasoline and Diesel Fuel

The MDR Water Probe Indicator detects the presence of water in your gas or diesel fuel tank. Fuel contaminated with water can lead to serious problems. It's better to be safe than sorry. Simply apply the MDR water probe detector on the dip stick, which turns red to show the exact level of water in your fuel tank. MDR's companion product, the Water Zorb, will remove any water.
