📋 Kit Contents

🔌 Function

Delivers high-pressure fuel from the injection pump to its cylinder's injector, maintaining injection pressure along a fixed, formed route. Each pipe is shaped for one cylinder position and must be fitted accordingly.

⚠️ Common Signs of Failure

• Fuel leakage at the union nuts
• Cracking or chafing where the pipe passes a clamp or bracket
• Single-cylinder misfire or uneven running
• Damaged or rounded union threads
• Pipe bent out of shape during previous service

🛠️ Service Notes

• Confirm the cylinder position before ordering; weight alone will not distinguish it from the cylinder-4 kit
