original 20R-8057 C7 Diesel Fuel Injector Pump 263-8218 295-1408 238-8091 for Cat E324D E325D E329D Engine Spare Part  original new injector

The 20R-8057 Original Reman fuel injector is engineered specifically as an OE-matching replacement for the C7 6-cylinder inline diesel engine platform, including C7 and C7 ACERT variants used in medium-duty trucks, buses, construction equipment, excavators, wheel loaders, generator sets, and other industrial machinery. The injector carries cross-reference coverage for 10R-4761, 222-5961, 222-5959, 233-3536, 236-0973, 241-3238, 243-4502, 295-1408, 328-2583, 387-9430, 293-1408, and EX634761, allowing direct fitment on C7 engines produced for the 2004-2009 model range and supporting fleet maintenance, engine rebuilds, and complete set replacement across six-cylinder applications.
Built through the Reman process, this injector uses specialized metallurgy, precision manufacturing, and critical engineering updates to deliver accurate fuel metering, consistent atomization, and reliable combustion on today's low-sulfur and low-lubricity diesel fuels. Each unit is thoroughly tested for flow rate, internal leakage, spray pattern, and dynamic response, helping restore original power output, fuel economy, and exhaust characteristics. The reman format provides a cost-effective solution for diesel repair shops, fleet operators, parts distributors, and engine rebuild workshops seeking OE-level performance with proven reliability for C7 engine maintenance programs.
Proper installation and maintenance are essential for long service life. Operators should follow service manual torque values, install new seals, O-rings, and washers, prime the fuel system, and perform post-installation checks for leaks, idle quality, misfire, smoke, fuel pressure, and diagnostic trouble codes. Routine practices such as fuel filter replacement, water separator draining, clean fuel handling, air filter service, and periodic cylinder balance and return flow testing help prevent common symptoms including hard starting, rough idle, white or black smoke, power loss, excessive consumption, and uneven cylinder output, ensuring consistent performance throughout the C7 engine's operational life.
