“I have been using the DAVCO product for five years now and would strongly recommend it. I first installed four of the DAVCO 243 fuel filter assemblies on four school buses to monitor their effectiveness. I was shocked at how well this system worked for our application. Most aftermarket systems do not do well on the school bus.”
