FAQ

Q1: How do I verify if this 7123-340W head rotor is compatible with my fuel pump?

A: First, check the model number on your existing DPA fuel pump head rotor. It should match “7123-340W” and “4/9.5R”. If you are unsure, please provide us with a photo and the serial number of your current part. Our technical team can cross-reference it to confirm compatibility before you place an order.

Q2: What are the key signs of a failing fuel pump head rotor that would require replacement?

A: Common symptoms include hard starting, engine misfiring, a noticeable loss of power, black smoke from the exhaust, or fuel leaks from the pump housing. If you experience these issues, it is recommended to inspect and test the head rotor as part of a comprehensive fuel system diagnosis.

Q3: What is the recommended installation procedure for this stainless steel head rotor?

A: Installation should be performed by a qualified diesel technician. The process typically involves removing the fuel pump, disassembling the pump head, and carefully replacing the old rotor with the new one. It is crucial to ensure proper lubrication during assembly and to prime the fuel system after installation to prevent air locks. We recommend consulting the specific service manual for your fuel pump model.
