As many Duramax owners know, the stock fuel filter on their truck is not only expensive to replace, but is in a very awkward and hard to reach location. With a FASS Fuel System or other aftermarket filtering system downstream of the stock filter, we are able to totally delete the OEM Filter, thus eliminating the time and costs associated with a new filter and install every 5-10K miles. Our revolutionary bowl design will screw on in place of the stock filter allowing fuel to flow through unrestricted while also offering a gauge port if the end user wishes to monitor fuel pressure!
After the installation of a FASS Fuel Air Separation System the factory fuel filter is no longer needed and can be easily removed by using this Factory Fuel Filter Delete Kit.
Note: This system must be used with another form of fuel filtration, such as our Titanium FASS Fuel Air Separation System.
