Detailed Product Overview

Gates EMH337 is engineered as a direct replacement for the crankcase ventilation hose that runs from the PCV valve to the intake on select Ford trucks and cars. The molded plastic body, OE-exact dimensions, and clip-on connector design help maintain the original emission control hose routing and connection integrity. Use EMH337 when servicing a Ford F-150 or Ford Mustang with a worn, cracked, or disconnected breather hose in the crankcase ventilation system.

This part cross-references Ford BR3Z 6A664 A for the same application.

Common Problems This Part Can Address

• Cracked or brittle crankcase breather hose
• Loose or broken clip-on hose connections
• Vacuum leaks in the PCV-to-intake path
• Improper crankcase ventilation routing
• Emission system performance issues caused by hose failure

Installation Notes and Tips

Verify the hose routing before removal and compare the original connector style to the new part. EMH337 uses clip-on ends and molded construction, so proper alignment at both connection points is important for a secure seal. Confirm fitment by year, make, model, and PCV valve to intake position before installation.
