Detailed Description

Standard Ignition V637 is a replacement crankcase breather hose designed for 2008-2011 Ford F-250 Super Duty and 2008-2011 Ford F-350 Super Duty models. This hose routes crankcase vapors through the emission control system and helps maintain proper ventilation path integrity when the original hose is cracked, brittle, or no longer sealing correctly. The two-connector layout and included clamp support a straightforward hose-to-hose or hose-to-port connection in the specified application. This part cross-references Gates EMH149 for the same application.
