⚙️ Key Features

• Supersedes 840486
• 0.016 kg
• 23 applications on the D series
• Fuel System group

🔌 Function

Seals a fuel system joint, keeping diesel in the circuit and stopping air being drawn into the suction side.

⚠️ Common Signs of Failure

• Diesel weeping from the joint or a wet, stained flange
• Strong fuel smell in the engine space
• Hard starting or rough running from air drawn in at the joint
• Air bubbles visible in a clear fuel line
• Gasket found hardened, shrunk or swollen when the joint is opened

🛠️ Service Notes

• A fuel leak is a fire risk — clean up spilt diesel and check the joint again once the engine has run and warmed
• Renew the gasket rather than re-tightening the joint, since over-tightening distorts the faces and makes the leak worse
