Detailed Product Description

The Baldwin BF1395-SP fuel water separator filter is engineered to separate water from diesel fuel, preventing contamination that can cause engine damage. With a height of 11 7/32 inches and an outside diameter of 4 9/32 inches, this filter fits securely in Freightliner truck fuel systems.
