Perkins original 203-3464 Common Rail Diesel Injector for C10 C12 Excavator Engine Fuel Injector Assembly Replacement for OEM original new injector

The Perkins C12 Fuel Injector 203-3464 is an industrial-grade replacement fuel injection component engineered for the Perkins C12 series 12.0-liter inline six-cylinder diesel engine. Designed as a direct-fit OEM specification unit injector, it serves heavy-duty trucks, buses, construction machinery, mining equipment, agricultural machinery, marine diesel engines, generator sets, industrial power units, and off-road equipment. With broad cross-reference compatibility including 10R-1003, 212-3463, 317-5278, 281-7152, and 20R-0055, this injector supports B2B diesel parts distribution, fleet maintenance operations, and engine rebuilding workshops handling Perkins C12 platforms.

This unit injector delivers precision fuel metering and fine atomization to maintain stable idle performance, support power recovery, contribute to improved fuel economy, and help reduce exhaust smoke across commercial marine ratings of 340–490 bhp at 1800–2300 rpm. Its heavy-duty construction ensures engine-specific fitment and replacement-ready installation for demanding industrial environments. Built to OEM standards, it provides dependable injection performance suitable for export supply to diesel parts wholesalers and heavy equipment service providers worldwide.

Proper installation requires confirming the injector part number, engine model, injector code, and engine serial number before fitting. O-rings, sealing washers, and related seals should be replaced, and fuel filter, fuel quality, fuel pressure, and injector bore condition inspected. Use proper tools and follow the official Perkins service manual for torque values and installation sequence. After installation, check for fuel leaks, abnormal noise, misfire, smoke, and diagnostic fault codes, then perform a final idle and load test to verify injector performance.
