Description

When your diesel engine starts acting up—rough idle, power loss, or hard starting—chances are good that water or contamination in the fuel system is the culprit. Water in diesel fuel causes everything from injector corrosion to fuel system failures, and today’s ultra-low sulfur diesel tends to hold more moisture than older fuel formulations. This Baldwin fuel water separator filter catches those problems before they reach your engine.

Key Features

Dual-stage filtration removes both water and particulate contamination in one step
4 3/32 inch length and 3 3/8 inch diameter fits factory specifications perfectly
Attached grommet and ring provide secure mounting and proper sealing
Quality Baldwin construction handles vibration and pressure fluctuations
Direct replacement design means no modifications or adapters needed

Built for Real Work

This filter is engineered for Cummins ISB engines found in everything from Dodge pickup trucks to commercial delivery vehicles and work trucks. Whether you’re pulling trailers on the highway, making deliveries around town, or using your truck for heavy-duty farm work, clean fuel keeps these engines running strong and responsive when you need power most.

Made to Last

Commercial and agricultural applications put fuel systems through the wringer—temperature swings, vibration, and varying fuel quality all take their toll. Baldwin builds this filter with media that maintains proper flow while capturing contaminants, and the housing construction stands up to the pressure and abuse of daily operation.

Installation Notes

This is a straight replacement for your original filter—same dimensions, same mounting, same performance. Prime the new filter with clean diesel before installation to minimize air in the system, and always replace the sealing surfaces to prevent leaks. Keep an eye on the water collection bowl if your system has one, and drain it regularly to prevent overflow.
