Carquest Premium Fuel/Water Separator Spin-On with Open Port for Bowl is engineered to provide reliable protection for today’s diesel engines by removing both particulate matter and water before they can harm sensitive injectors or fuel pumps. Built to OE-quality standards, this filter is designed for use with bowl-equipped modules and helps maintain clean, efficient fuel delivery across extended service intervals.

Specifications include a spin-on separator with 1-14 thread, outer diameter of approximately 4.25" (108 mm), and length of 5-7/32" (132.6 mm). Designed for effective water separation, this filter often includes drain or sensor variants depending on housing requirements.

Cross-references include Donaldson P551852, Fleetguard FS19687, Racor R60T/R60TDMAX, Baldwin BF1223-O, and NAPA 3231, along with several OE numbers, giving you multiple reliable alternatives.

Commonly used in Freightliner Cascadia, International ProStar and WorkStar, Kenworth T-series, Peterbilt 300/500 series, and Volvo VNL trucks equipped with 1-14 threaded fuel/water separator modules. Fitment should always be confirmed by housing design and sensor configuration before installation.
