Perkins original Fuel Injector Assembly 20R-8045 Replacement for OEM C13 C15 C18 Engine D350GC D400GC Excavator Spare Parts original new injector

The Perkins C13 fuel injector 20R-8045 is engineered as a direct replacement for Perkins C13 and C13 ACERT diesel engines used in heavy duty trucks, construction machinery, mining equipment, generator sets and industrial power units. Designed to match the original MEUI-family electronic unit injection system, this injector delivers precise fuel metering and controlled injection timing to support stable combustion across industrial ratings from 287 to 400 kW (385 to 536 hp) and generator set ratings from 320 to 400 ekW at 60 Hz. Specialized metallurgy, updated manufacturing processes and full bench testing help the injector perform reliably in low-sulfur and low-lubricity diesel conditions commonly found in international markets.

As a reman-style assembly, the 20R-8045 integrates the C11/C13 injector number family geometry, heavy duty construction and high atomization performance required by 12.5L inline six-cylinder engines. Cross references 20R-8045, 20R8045, CA20R8045, 253-0608, 2530608, CA2530608, 10R-1274, 10R-7236, 10R-2977, 10R-3262, 20R-8046, 20R-2437, 239-4907, 239-4908, 249-0705, 249-0708, 249-0713, 292-3666, 332-1419 and 348-4090 allow flexible stocking for distributors, fleet operators and service shops. Single-injector and full-set replacement options help control repair cost and reduce sourcing risk while restoring engine power, improving combustion stability and reducing rough running.

For best service life, operators should replace the fuel filter on schedule, use clean diesel, drain the water separator regularly, keep the fuel tank clean, maintain correct engine oil grade, inspect electrical connectors and wiring, scan ECM fault codes, and perform return flow or cylinder balance testing when hard starting, smoke, misfire, power loss, fuel knock, excessive exhaust temperature or fuel-in-oil symptoms appear. Repeated injector failure should prompt a full fuel system inspection for contamination, metal debris or installation problems before reassembly.
