original 20R-1267 Common Rail Fuel Injector for 994D Diesel Engine Parts High Pressure Fuel Nozzle Replacement for OEM 392-0203 3920203 20R1267 original new injector

Engineered for demanding heavy-duty diesel applications, the 20R-1267 Fuel Injector is a precision-built replacement component designed for the 3512B engine within the 3500 Series family. This injector assembly is interchangeable with a broad range of OEM and aftermarket cross numbers including 392-0203, 10R-1276, 0R-9796, OR-9796, 229-0202, 250-1303, 386-1755, and 172-4677, ensuring reliable sourcing flexibility for global fleet operators and industrial procurement teams.

The 20R-1267 features a precision-machined nozzle for optimal fuel atomization, hardened internal components for extended service life, and corrosion-resistant materials suited to harsh operating environments. Each injector is manufactured to OEM calibration standards and tested for stable delivery under high-pressure conditions, supporting consistent combustion efficiency across prime and standby diesel generator sets, marine propulsion and auxiliary systems, mining equipment, oil & gas drilling rigs, and industrial backup power installations. Its robust construction addresses common failure modes such as hard starting from internal leakage, white smoke from poor atomization, black smoke from overfueling, rough idle from spray malfunction, power loss from restricted flow, and high fuel consumption from pressure imbalance.

Recommended service intervals include fuel filter replacement every 250 hours, fuel system inspection every 500 hours, injector performance and pressure testing every 1,000 hours, and full bench testing every 2,000 hours. This maintenance-friendly design makes the 20R-1267 a dependable choice for B2B buyers seeking long-term operational reliability.
