261-2293 2612293 Exhaust Rocker Arm for C11 Engine

High-quality exhaust rocker arm designed specifically for C11 engines, offering reliable performance and durability.

Pro-Tip: Since the pump works within the HEUI system, ensure your engine oil is fresh and of the correct viscosity (e.g., 15W-40). Dirty oil will cause the pump to fail prematurely as it relies on oil pressure to actuate.

• System Decontamination (System Flush)
  Before removing the old pump, drain and flush the fuel tank and fuel lines. Metal shavings from a failed pump can circulate and instantly destroy your new unit.
• Inspect the Transfer Pump & Filters
  Replace both the primary and secondary fuel filters. Ensure you use high-efficiency (2-micron) filters. Inspect the fuel transfer pump for wear; if it's weak, the high-pressure pump won't receive enough fuel.
• Oil Quality Check
  Change the engine oil and oil filter. HEUI pumps use engine oil to create high-pressure fuel injection. Dirty or incorrect viscosity oil (e.g., using 10W-30 instead of 15W-40 in high temps) will cause immediate performance issues.
• Lubrication on Install
  Apply clean engine oil to the O-rings and the pump drive gear. Warning: Never dry-start. Fill the pump with clean diesel through the inlet before connecting the lines.
• Torque Sequence
  Tighten the mounting bolts in a cross-pattern to the manufacturer's specified torque (refer to C7/C9 service manual).
