FAQ

Q: Is this pump a direct replacement for my existing Bosch CP3 pump?
A: Yes, this pump is manufactured as a direct OE replacement. However, it is critical to verify your original pump’s part number (e.g., 0445020037 or 0445020005) to ensure exact compatibility with your engine’s mounting, fuel line connections, and ECU programming.

Q: Do I need to recalibrate the engine ECU after installation?
A: For most direct OE replacement pumps, no ECU recalibration is required. However, if you are replacing a pump on a high-performance or modified engine, or if the new pump has a different flow rating, a professional calibration may be necessary to optimize performance and fuel economy.

Q: What maintenance is recommended for this fuel injection pump?
A: The most important maintenance step is ensuring a clean, water-free fuel supply. Always use high-quality fuel filters and replace them according to your engine manufacturer’s schedule. Contaminated fuel is the primary cause of CP3 pump failure. We also recommend using a fuel additive to provide additional lubrication for the pump’s internal components.
