Description
Fleetguard FK13850NN premium NanoNet fuel-filter kit for 2014-and-later Detroit Diesel DD13, DD15, and DD16 engines, replacing the earlier Fleetguard FK13834 service kit. Built around the NanoNet FS53034NN primary element with the gaskets and seals required for a complete fuel-filter housing service. NanoNet media captures water and sub-4-micron contaminants ahead of the high-pressure fuel system, protecting common-rail injectors on Freightliner Cascadia, Western Star 4900/5700, and Mercedes-Benz Actros applications using DD-platform power. Replaces Detroit A4700903151.
