🔌 Function

Separates water and filters particles from the diesel supply before fuel reaches the engine injection equipment.

⚠️ Common Signs of Failure

• Hard starting or power loss under load
• Low fuel-supply pressure or restriction warnings
• Water visible in the separator bowl
• Fuel leakage around the centre seal or bowl
• Filter service interval exceeded

🛠️ Service Notes

• Work clean — cap or cover open connections and keep dirt out of the housing, because contamination introduced at a filter change goes straight to the injection equipment
• Where the design allows it, fill the new filter with clean fuel before fitting, and smear the sealing ring with clean fuel rather than grease
• Renew every seal supplied with the filter and tighten to the marking on the filter or the figure in the workshop manual for your engine; over-tightening distorts the seal and causes leaks
• Prime and bleed the system by the procedure for your engine before cranking, then run up and check the sealing faces for weeps
• Drain and inspect any water trap at the same time and note what comes out — water or dark sludge means the tank and pre-filter need attention too
