Engine Crankcase Breather Hose for Mustang

Key Features

• Rubber construction for engine bay use
• Protective sleeve included for added abrasion resistance
• Two-port hose design
• No clamp included
• No mounting hardware included
• Direct-fit replacement for 2001-2004 Ford Mustang

Product Details

This Standard Ignition V778 crankcase breather hose is intended for the crankcase ventilation system and is built to match the original hose-style routing used on 2001, 2002, 2003, and 2004 Ford Mustang models. The rubber construction helps maintain a secure connection path between ventilation points, while the protective sleeve adds an extra layer where the hose is exposed to heat and wear. This part cross-references 2-9849 and KCV112 for the same application.

Common Issues It Can Help Address

• Cracked or split breather hose material
• Oil vapor leaks from damaged ventilation routing
• Collapsed or hardened rubber hose sections
• Improper crankcase ventilation flow caused by hose deterioration
• Fitment problems from an incorrect replacement hose

Installation Notes

Verify hose routing against the original part before installation. Because no clamp is included, reuse or source the correct clamp style as needed for the vehicle. Inspect adjoining ventilation ports and nearby vacuum or breather connections for wear, contamination, or damage before completing the repair.

Quality Assurance

Standard Ignition supplies replacement ignition and engine management components for service applications, and V778 is built as a service replacement hose for the listed Ford Mustang fitment.
