FAQ

Q: How do I confirm this part is compatible with my specific DPA pump?
A: The most reliable method is to cross-reference the part number currently installed in your pump. Match it against the OEM numbers listed in the “OEM Cross-Reference” section above (7139-235S, 7180-593S, etc.). The pump must be for a 3/8.5R Head Roto configuration.

Q: What is the lead time for delivery to [North America/Europe]?
A: We process orders rapidly. Once dispatched, delivery to major destinations in North America or Europe typically takes 3-7 business days via express courier. Delivery times to remote areas may vary slightly.

Q: Is any special maintenance required after installing this new rotor head?
A: Yes. After installing any new fuel injection pump component, it is highly recommended to have the complete pump assembly professionally calibrated and tested on a pump test bench. This ensures proper injection timing, pressure, and overall engine performance. Always prime the fuel system to remove air after installation.
