iFJF part No.: FJ-TP3018. TP3018 Fuel Filter Premium Filtration for Duramax 6.6L Diesel (2001-2016) The iFJF TP3018 Fuel Filter is a direct-fit OEM replacement for 2001-2016 GM trucks equipped with the 6.6L Duramax diesel engine. Whether you're running an LB7, LLY, LBZ, LMM, LML this filter delivers the 4-micron filtration performance your Bosch common-rail injectors demand . A single grain of sand-sized contaminant can score an injector nozzle this filter prevents that. Available in 1-Pack ($49.99) or 2-Pack ($89.99 save $10) . The TP3018 is one of the most critical maintenance items on any Duramax. GM specifies replacement every 15,000 miles, but many owners change it every other oil change (10,000 miles) for extra protection especially if you fuel up at high-traffic stations or run biodiesel blends. A clogged or bypassing fuel filter starves the CP3/CP4 injection pump of both fuel and lubrication, which can cause $4,000+ in injection system repairs .
