Description
The ACDelco TP3018 is a direct OEM replacement fuel filter engineered for superior protection and long service life in your Duramax diesel truck.
With a 4-micron filtration rating, this filter traps dirt, rust, and water before they can enter your fuel system — helping to prevent injector damage and maintain peak engine performance.
This is the factory-correct filter for LB7, LLY, LBZ, LMM, and LML Duramax engines, trusted by GM dealerships and diesel professionals alike.
Maintenance Notes: Replace your fuel filter every 15,000–30,000 miles, depending on usage and fuel quality. Always prime your fuel system after replacing the filter on Duramax applications.
