CAT C9.3 High Pressure Common Rail Pump Solenoid Coil

The SO10 pump solenoid coil fits the high-pressure common rail fuel pump on Caterpillar C9.3 engines. A failed pump solenoid causes low rail pressure, derates and hard starting.

When to replace the coil

• Low rail pressure or pump solenoid fault codes
• Hard start or loss of power with good supply fuel
