FAQ

Q: How do I know which delivery valve size (e.g., 33A vs 39A) is correct for my fuel injection pump?

A: The correct size is determined by the specific model of your fuel injection pump. You must remove the old delivery valve and check the part number stamped on it. The “A” designation is a key identifier. If you are unsure, please contact our customer service with your pump’s model number and the old part number for verification.

Q: What is the installation process for this delivery valve?

A: Installation should be performed by a qualified diesel mechanic. The process involves disassembling the fuel injection pump head, removing the old valve holder, valve, and spring, cleaning the seat area, and installing the new delivery valve assembly with the correct torque specification. It is critical to maintain a clean working environment to prevent contamination of the fuel system.

Q: How can I maintain the delivery valve for optimal performance and longevity?

A: The primary maintenance factor is using clean, high-quality diesel fuel and replacing your fuel filters regularly. Contaminants in the fuel are the main cause of delivery valve wear. During pump overhauls, the delivery valve should always be replaced along with the pumping elements (plunger and barrel) to ensure matched performance and prevent fuel leakage into the fuel line.
