🔧 Kubota Fuel Filter / Water Separator Wrench – 10-Tooth (Small) 

This custom 10-tooth fuel filter / water separator wrench is designed for Kubota diesel generator applications that use the small fluted 10-tooth separator bowl. It provides a positive, slip-free grip for easier removal and installation during fuel system maintenance.

Unlike strap wrenches or adjustable tools, this wrench is shaped to fully engage all 10 teeth on the separator cup, helping reduce rounding, slipping, and damage — especially on tight or stubborn filters.
