Return hoses operate continuously in the fuel environment.
Over time, material aging may affect system condition.
Aging Can Influence Performance
Potential concerns include:
- cracking;
- leakage;
- connection weakness;
- material degradation.
Inspection Matters During Service
When injectors are serviced, surrounding fuel connections should also be reviewed.
Conclusion
Injector maintenance includes the surrounding fuel system, not only the injector body.
