Description
Delphi 333-4004 replacement injector solenoid coil for Caterpillar 3406E and C-series MEUI (mechanically-actuated, electronically-controlled unit injector) fuel injectors — the electromagnetic actuator that opens the spill / control valve to time and meter each injection event. Used by injector remanufacturers and shops servicing Cat 3406E, C10, C12, C13, C15, C16, and C18 EUI injector bodies, replacing Cat OEM solenoid 333-4004 / 3334004.

Applications
This injector solenoid fits Cat MEUI / EUI fuel injectors on the following engines:
- Caterpillar 3406E (14.6L)
- Caterpillar C10 / C12
- Caterpillar C13
- Caterpillar C15 (including ACERT and Twin Turbo)
- Caterpillar C16
- Caterpillar C18
Representative on-highway and vocational vehicles using these engines:
- Peterbilt 379, 387, 389, 386 (3406E / C15)
- Kenworth W900, T800, T600 (3406E / C15)

- International 9900i and similar Class 8 chassis specifying Cat power
This is the solenoid coil only — it installs into a Cat MEUI / EUI injector during rebuild. Verify your injector body and which solenoid it specifies before ordering. Cat injector solenoid replacement is an injector-shop level repair requiring proper torque, sealing, and bench-test calibration.
