Common Symptoms of Injector Pump Leaks
When an injector pump begins to leak, it can manifest in several ways. Below are the most common symptoms to look out for:
- Fuel Leaks Near the Injector Pump
- The most obvious sign of an injector pump leak is visible fuel leakage. You may notice fuel pooling around the injector pump area, often near the seal or mounting points. This indicates that fuel is escaping from the system.
