🔌 Function

Carries engine oil under pressure to the instrument that reads it, so the gauge senses actual gallery pressure.

⚠️ Common Signs of Failure

• Oil pressure gauge reading zero, low or wildly erratic
• Oil weeping at the gauge end or the engine end union
• Tube kinked, crushed or chafed along its run
• Oil appearing behind the instrument panel
• Gauge slow to respond to a change in engine speed

🛠️ Service Notes

• Renew the sealing washers at both unions and avoid sharp bends when routing the tube
• A gauge reading zero is often this line rather than the pump, so check the tube before condemning anything expensive
