| No. | Question | Answer |
|---|---|---|
| Q1 | Which interchange part numbers can replace 319-0607? | 20R-0819 and 10R-8900 are fully interchangeable, same gear size, oil circuit layout and installation dimension, direct replacement without any modification. Made in China, full stock available, ship within 1-7 working days. |
| Q2 | After replacing 319-0607, equipment suffers hard cold start and power drop during heavy load? | Internal alloy steel plunger is worn or built-in pressure balance valve fails, cannot reach standard 4000PSI HEUI system pressure, whole fuel pump assembly needs replacement. |
| Q3 | Can this HEUI fuel pump fit small-displacement industrial engines? | Not interchangeable, small engines adopt mini low-pressure fuel pump with different gear teeth and oil flow parameters, incompatible with this medium-large displacement HEUI pump. |
| Q4 | What are unique advantages of this domestic replacement HEUI pump? | Fully matched OEM installation size and pressure parameters, complete multi-item high-pressure factory inspection, durable for long-time heavy mining operation, lower cost than original parts, stable delivery within 1-7 working days. |
| Q5 | Does this fuel pump need professional ECU calibration after installation? | After installation, run engine at idle speed for 15 minutes, the electronic control unit will automatically match the HEUI oil pressure curve, no extra bench calibration required for repair workshops. |
