🔌 Function

Carries oil from the sump to the pump inlet, with the strainer end held below the oil level so the pump has a flooded supply at all angles of heel.

⚠️ Common Signs of Failure

• Oil pressure falling away at idle or fluctuating under load
• Pressure that recovers when the sump is overfilled, pointing to a pickup drawing air
• Strainer mesh blocked with sludge, sealant or gasket debris
• Cracked or fractured pipe, often at the flange or a bracket
• Loose or missing pipe mounting allowing the pickup to move in the sump

🛠️ Service Notes

• Check the engine serial number before ordering — this pipe is superseded at 2203119085 and the later engines take a different part
• Clean the strainer and inspect the sump for the debris that blocked it, rather than just fitting a new pipe
• Renew the pickup joint seal or gasket at the same time, since an air leak here mimics a worn oil pump
