Product Overview
The NAKATU FF63042NN is an aftermarket spin-on diesel fuel filter intended as a replacement for Fleetguard FF63042NN in compatible high-horsepower diesel engine applications.
It is designed to help capture fine particulate contaminants, including dirt and rust particles, from diesel fuel before they reach sensitive fuel injection components. This type of fuel filtration is particularly important for large industrial diesel engines operating in demanding mining, construction and power generation environments.
The original Fleetguard FF63042NN is a NanoNet fuel filter developed for selected Cummins QSK and QST engine applications.

Applications
Fleetguard lists FF63042NN for selected Cummins QSK60, QSK60G, QST30 and GQSK60-GE engine applications.
A Fleetguard technical bulletin additionally identifies Cummins QSK23, QSK38, QSK50 and QSK60 engines as relevant applications for FF63042NN.
Published equipment applications include Liebherr R9400 mining excavators equipped with Cummins QSK50 engines, including selected model years from 2012 through 2023.
Additional published applications include Liebherr R9800 mining excavators with QSK60 engines, Hitachi EX3600-6 excavators with QSK60 Tier 2 engines, and Bharat Earth Movers BH85-1 equipment with QST30-C950 engines.
Not every machine in these model families uses the same filter. Exact fitment depends on the engine serial number, production year, filtration system arrangement and original equipment part number.
