Detailed Description

Gates EMH149 is an engine crankcase breather hose designed for emission control repair where the original hose has cracked, hardened, or lost its sealing ability.

What It Helps Fix

  • Cracked or brittle crankcase breather hose
  • Vacuum leaks in the crankcase ventilation circuit
  • Improper PCV routing caused by a damaged hose
  • Emission system performance issues related to hose failure
  • Oil vapor leakage from a deteriorated breather line

Installation Notes and Tips

Install EMH149 on the valve cover to PCV valve route specified for the vehicle. Confirm the push-in ends are fully seated and inspect the mating ports for wear, debris, or hardened seals before installation. Because this hose is molded to OE-style dimensions, verify routing against the original part before final assembly on your Ford F-250 Super Duty or Ford F-350 Super Duty.
