6. Latest technology trends
Recent industry data shows that the failure rate of electronic fuel pumps is 40% lower than that of traditional mechanical pumps. The new pump body adopts:
- Carbon brush motor design (life expectancy increased by 30%)
- Integrated pressure regulator (reduces points of failure)
- Intelligent diagnostic interface (can provide early warning of faults)
It is recommended that car owners give priority to original upgraded models when replacing oil pumps to obtain longer service life and better stability.
