Product Overview
Water in diesel fuel can cause hard starting, rough running, corrosion, injector damage, and expensive pump wear. This separator is the service part to replace when the bowl shows contamination, the filter is restricted, or scheduled maintenance is due on a matching Kubota system.
Drain contaminated fuel and clean the bowl or housing. Installing a new filter without removing the water source only postpones the problem.
