Specs At A Glance

Good To Know

Q: How often should this fuel filter be replaced on a Duramax engine? A: Standard service intervals call for replacement every 15,000 to 25,000 miles depending on fuel quality and driving conditions, with more frequent changes recommended when running high-mileage routes with varying diesel sources.

Q: Does this filter include the o-ring and water sensor seal for the housing? A: Many replacement elements are sold as filter-only, so check whether your kit includes the housing seals or if those need to be sourced separately to ensure a leak-free installation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
