Step-by-Step Installation Guide

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.

1. 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.

2. 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.

3. 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.

4. 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.

5. Torque Sequence
Tighten the mounting bolts in a cross-pattern to the manufacturer's specified torque (refer to C7/C9 service manual).

Troubleshooting Guide

Issue	Possible Cause	Solution
Engine Won't Start	Air trapped in the fuel lines	Bleed the fuel system thoroughly.
Low Fuel Pressure	Clogged fuel filters or a leaking SCV (Suction Control Valve)	Replace filters; inspect the SCV for debris.
Black Smoke / Power Loss	Contaminated fuel causing plunger wear	Drain fuel tank; use high-quality diesel.
Loud Knocking Noise	Improper timing or loose mounting bolts	Re-calibrate the timing and check bolt torque.
