- 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 primary and secondary fuel filters. Use high-efficiency (2-micron) filters. Inspect the fuel transfer pump for wear; if 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 will cause immediate performance issues.
- Lubrication on Install: Apply clean engine oil to the O-rings and pump drive gear. Warning: Never dry-start. Fill the pump with clean diesel through the inlet before connecting the lines.
| Issue | Possible Cause | Solution |
|---|---|---|
| Engine Won't Start | Air trapped in fuel lines | Bleed the fuel system thoroughly |
| Low Fuel Pressure | Clogged fuel filters or leaking SCV | Replace filters; inspect 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 timing and check bolt torque |
