This replacement element has the capability of filtering out particles down to a size of 2 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. Although we normally recommend going with a 10 micron filter a 2 micron can be used, just make sure you have plenty of spares as they are bound to clog up much more quickly than their 10 micron counterpart.
