• Supersedes part number 3889039
• Listed for 8 D series applications

🔌 Function

Carries diesel between two connections in the fuel circuit while absorbing the movement between them, using the factory length and routing so the hose is neither stretched nor left to chafe.

⚠️ Common Signs of Failure

• Smell of diesel in the engine space, or a wet, dust-caked patch under the hose
• Hard starting, misfiring or air drawn into the system where a suction hose is weeping
• Outer cover cracked, or the hose hard and glazed near the ends
• Inner liner found perished or swollen, shedding particles towards the filters, on strip-down

🛠️ Service Notes

• It replaces 3889039, so an engine listed with the earlier number takes this hose
• Renew the sealing washers or clamps at each end, then bleed the system and check for weeps at working pressure
• A diesel leak in an engine space is a fire risk: do not run the engine on a weeping hose
