Duramax Water-in Fuel Sensor Double Sided Wrench

• Two tools in one • 42 mm 6 side fits 2011 to current years • 40 mm 12 side fits 2001 to 2010 • Used every time a fuel filter is replaced • Made in U.S.A. • When replacing the fuel filter on a 2001 to current GM DURAMAX light duty truck, the water-in-fuel sensor located in the bottom of the filter must be removed and reused in the new filter. • This wrench has two sides, one designed to fit the odd shaped 40mm, 12 sided sensor found on 2001 to 2010 trucks, the other end fits the 42mm, 6 sided sensor on the 2011 to current trucks. • This sensor is made of plastic and easily damaged by using pliers and other nonspecific designed tools, so using the correct tool is a must.
