Caterpillar 462-0470 C32 Marine Fuel Injector
The Caterpillar 462-0470 fuel injector, also searched as Caterpillar 4620470, is used in selected Caterpillar C32 marine engine applications.
The injector is a precision component of the C32 fuel system, controlling fuel delivery into the combustion chamber. Correct injector identification is important because different C32 engine arrangements and configurations can require different injector assemblies.
The 462-0470 should not be considered a universal injector for every Caterpillar C32 engine.
For accurate identification, provide:
Engine model + Engine Serial Number (ESN) + arrangement number + existing injector part number

These injector references should not automatically be considered interchangeable.
462-0470 ≠ 356-1367 ≠ 356-1373 ≠ 276-8307
Likewise, the corresponding Reman references are different:
30R-1990 ≠ 20R-9945 ≠ 20R-5353 ≠ 10R-7231
Correct selection depends on the specific C32 engine configuration.

Why Correct C32 Injector Identification Matters
Caterpillar C32 engines have been produced in multiple configurations. Two injectors can therefore belong to the C32 family without being suitable replacements for one another.
Before ordering 462-0470 or 30R-1990, confirm:
- Caterpillar C32 Engine Serial Number
- Serial-number prefix
- Engine arrangement number
- Existing injector part number
- Engine application
- Required quantity
- New or Reman requirement
Correct identification helps prevent an injector intended for a different C32 configuration from being ordered.
