- LB7 Engine, VIN 1; Cylinders 2 & 7 - One line required per cylinder. Recommend replacement any time injector is serviced or replaced.
- Fuel Injector High Pressure Line
- A common problem on the Duramax LB7 engine is contamination of the fuel fittings resulting in injector failure when serviced. Corrosion can form between the line and injector nut and fall into the injector when the line is removed or installed. Replacing the line at time of injector replacement or service is highly recommended to reduce injector failure due to contamination.
