I have a Bobcat X320 excavator with a 3 cylinder Kubota engine. Noticed that I was intermittently losing power to the engine. I purchased a new fuel filter, filled it full of fuel and installed. Let it run for about 5 minutes then tried to move it. It would start to lose power whether it was moving or not. My assumption at this point is that one or more fuel injectors need cleaning. Did some searching on line on how to clean fuel injectors. This is a Diesel engine about 30 years old. Some suggested putting an additive in the fuel tank like SeaFoam or equivalent that is designed for Diesel engines. Another suggestion was to remove the fuel filter, empty out the diesel and fill with the same fuel additive. Start the engine and run for 2 minutes, turn off the engine and let the additive sit in the system for 15 minutes then start engine and run for 30 minutes The last suggestion was to remove the injectors and let the tip soak in carburetor cleaner. Blow the injector out using air after its been in the cleaner for a couple of hours. Then test by spraying brake fluid through the injector to check pattern. They actually used wire from a wire brush to clean the tiny holes that the carburetor cleaner did not open up. So what have you done that has been successful? I assume that not all injectors are the same so the method for cleaning and testing may vary
