🔌 Function

Seals a fuel system joint, holding diesel in the circuit, at a controlled thickness of 0.25 mm.

⚠️ Common Signs of Failure

• Diesel weeping from the joint or a fuel-stained flange
• Fuel smell in the engine space
• Hard starting or rough running from air drawn in at the joint
• Gasket found crushed, torn or well under its stated thickness
• Bubbles visible in a clear fuel line

🛠️ Service Notes

• Order by the stated 0.25 mm thickness — a different thickness will alter the joint even if it seals
• Treat a fuel leak as a fire risk and re-check the joint once the engine has run warm
