Installation
Parts that must be replaced: high pressure fuel line between injection pump and injection rail.
Attention!
- Before installing the high pressure fuel line, lightly coat the nut threads with oil from the tube included in the new parts kit.
- Be careful not to get oil into the high pressure fuel lines.
- Do not lubricate the high pressure fuel lines supplied without a bottle of oil, these high pressure fuel lines are already lubricated.
- Remove the plugs immediately before installing the part in place.
