The Injector Dynamics Replacement Fuel Filter is available for the ID F750 fuel filter setup. This is available for separate purchase for those of you who need to replace your fuel filter if your current filter is worn beyond regular servicing. This filter features a high level of contaminant while maintaining low restriction to flow.  At a flow rate of 750 liters per hour, the filter in the ID750 will hold five grams of contaminant before requiring a replacement. Check out the Delta P Indicator for the current condition of the filter element in your ID F750.
