Doc's Diesel Fuel Filter for 5.0L Cummins Nissan Titan XD 2016-2019 — 3µm, 96.92% Efficiency

Doc's Diesel Fuel Filter for the 5.0L Cummins in 2016–2019 Nissan Titan XD is a third-party tested replacement that captures contaminants down to 3 microns with 96.92% efficiency.

This fuel filter is engineered specifically to match the fuel system needs of the 2016–2019 Nissan Titan XD equipped with the 5.0L Cummins diesel. It’s independently tested so you can rely on verified particle removal performance rather than untested claims. The filter’s design separates water and traps dirt, rust, and debris to help protect fuel pumps, injectors, and other downstream components.

How does this filter improve fuel system protection?

By removing very fine particles and separating water, the filter reduces abrasive contamination that accelerates wear in fuel system components. Cleaner fuel helps maintain consistent fuel pressure and injector performance, which supports efficient combustion and stable engine operation.

• Removes particles down to 3 microns, with 96.92% verified efficiency
• Separates and sheds free water to prevent corrosion and microbial growth
• Traps rust, dirt, and debris to protect pumps and injectors

Will this fit my truck and how do I confirm fitment?

This replacement is built for Nissan Titan XD models with the 5.0L Cummins engine from 2016 through 2019, but some vehicles have multiple configurations. Always use the fitment card on the product page and compare OE or current filter numbers to be certain before ordering.

• Designed for 2016–2019 Nissan Titan XD 5.0L Cummins engines
• Cross-references OE numbers 16403-EZ40A and 16403-EZ41A
• Interchanges: Wix WF10441/WF10442, Baldwin PF46140, Premium Guard DF99199/DF99200

How often should I replace the filter and what service practices help extend fuel system life?

Replacement intervals depend on driving conditions and your vehicle manufacturer’s warranty guidelines. Typical guidance is to replace the fuel filter every 5,000 to 10,000 miles, with 15,000 miles as a maximum under ideal conditions; inspect earlier if you tow, run in dusty environments, or notice performance changes.

• Recommended replacement: every 5,000–10,000 miles; do not exceed 15,000 miles
• Inspect when towing, off-roading, or after extended idling in dusty conditions
• Drain water separators and follow manufacturer service steps during changes

What quality checks and interchange options should I be aware of?
