FAQ

Q1: How do I confirm this metering valve fits my DPA pump?
A: Check the existing part number on your pump head rotor. If it matches 7123-490E, 7139-559D, or 7182-621E, this valve is a direct replacement. For universal fitment, ensure your pump uses a standard DPA metering valve design.

Q2: What is the installation procedure for this metering valve?
A: Installation should be performed by a qualified diesel technician. Typically, it involves removing the pump head, replacing the old metering valve, and reassembling with proper torque specifications. Always refer to your pump’s service manual for detailed instructions.

Q3: How can I maintain the metering valve for long-term performance?
A: Use clean, high-quality diesel fuel and replace fuel filters regularly to prevent contamination. Inspect the valve during pump overhauls and replace if wear or damage is detected. Proper maintenance extends valve life and ensures consistent engine performance.
