ACDelco TP3018B Professional OEM Duramax 6.6L Diesel Fuel Filter with Seals

The ACDelco TP3018B is a GM OEM-quality spin-on fuel filter engineered specifically for the 6.6L V8 Duramax diesel engine. Designed, engineered, and tested to rigorous GM standards, this filter delivers the same factory-level protection and fit as the original component installed at the plant.

Key Features:

• OEM-grade filtration — traps dirt, rust, water, and paint particles before they can enter the fuel delivery system or damage sensitive injectors
• Multi-layer filter media — provides high-efficiency contaminant capture for improved engine performance and extended fuel system life
• Spin-on design — straightforward replacement with included seals for a proper, leak-free installation
• Steel-cased construction — durable housing built to withstand the demands of heavy-duty diesel operation
• Updated design — incorporates GM running-change improvements for enhanced water separation efficiency over earlier filter versions
• GM-backed quality — manufactured to OE specifications for fit, form, and function

Regular fuel filter replacement is a critical part of Duramax diesel maintenance. Contaminated fuel is a leading cause of injector wear and premature fuel system failure. The TP3018B helps maintain steady fuel pressure and protects high-pressure common-rail injection components.
