Fuel Injection Needle Sleeve for Diesel Tractor Injection Systems SKU: QT0750115400

A worn needle sleeve in your injection pump creates havoc with fuel delivery—causing rough idle, hard starting, and uneven power that makes your tractor struggle with jobs it used to handle easily. This precision sleeve guides the injection needle valve for proper fuel metering, restoring the smooth operation and reliable power your diesel engine was designed to deliver.

Why Precision Matters

• Exact-fit design maintains proper needle valve guidance for accurate fuel delivery
• Premium materials resist wear from high-pressure diesel fuel and constant operation
• Precise tolerances restore proper fuel timing and prevent internal leakage
• Built to handle the extreme pressures and vibration that eventually wear out original components

When injection pump components fail, the entire fuel delivery system suffers. This needle sleeve is engineered to restore the tight tolerances needed for optimal diesel performance. With over 55 years of diesel expertise, S&H Parts can help confirm fitment for your specific injection pump application.
