This replacement element has the capability of filtering out particles down to a size of 10 microns. Be careful which filter you use. There are several replacement elements available that look identical. For example, there is what appears to be the same filter that only filters down to 30 microns. It leaves particles in the fuel that are too big and may clog the engine's filter. Another version filters to only 2 microns. This is filtering particles from the fuel that are so small it may clog almost immediately leaving you without power soon after replacement.
