Professional diesel mechanic or fuel system specialist installation is essential:

1. Ensure engine is cool - Allow the engine and fuel system to cool completely
2. Disconnect battery - Always disconnect the negative terminal before working
3. Relieve fuel pressure - Follow manufacturer procedure to relieve pressure in the common rail system
4. Clean the work area - Fuel system cleanliness is critical - clean all lines and fittings before disassembly
5. Disconnect fuel lines - Carefully disconnect high-pressure lines and low-pressure supply/return lines; cap openings to prevent contamination
6. Disconnect electrical connectors - Unplug the fuel metering unit and any sensor connectors
7. Remove drive coupling - Disconnect the pump drive gear or coupling from the engine timing gear
8. Remove mounting bolts - Unbolt the injection pump from the engine block or mounting bracket
9. Remove old pump - Carefully withdraw the old pump; note the orientation of the drive key and coupling
10. Clean mounting surface - Remove all old gasket material and debris from the mounting flange
11. Install new pump - Position the new pump with the Woodruff key and coupling block aligned; hand-start mounting bolts
12. Torque mounting bolts - Tighten bolts to manufacturer torque specifications
13. Reconnect fuel lines - Attach high-pressure and low-pressure lines with new seals; torque fittings to specification
14. Reconnect electrical connectors - Plug in the fuel metering unit and sensor connectors
15. Prime the fuel system - Operate the hand primer or crank the engine to prime the fuel system
16. Start and test - Start the engine; check for fuel leaks, proper rail pressure, and smooth operation
17. Check for codes - Use a diagnostic scanner to verify no fuel system trouble codes
