Fuel Filter Head Blanking Plug Kit for Diesel Fuel Systems SKU: QT61709

A missing or damaged blanking plug in your fuel filter head creates multiple problems—air enters the system causing hard starts and rough running, fuel leaks contaminate your work area, and dirt can infiltrate the clean side of your fuel system. This blanking plug kit restores proper sealing to unused ports in your fuel filter head, keeping your diesel fuel system functioning as designed.

Why Proper Sealing Matters

• Prevents air infiltration that causes fuel system prime loss
• Eliminates fuel leaks from unused fuel filter head ports
• Blocks contamination entry points that could damage injection components
• Includes multiple sizes to cover various filter head configurations

When fuel filter head ports aren't properly sealed, your tractor suffers from air locks, fuel contamination, and messy leaks.
