Hello. checking a clogged filter is elementary simple. I check it with a pressure gauge. To do this, take a pressure gauge, connect it to the fitting located on the fuel injector. Start the engine. Measure the pressure of the combustible mixture. If the value is lower than the parameter specified by the manufacturer, then the filter is not working properly. So it was on my Dodge.
