Original C7 Fuel Pump Injector 387-9427 263-8218 387-9429 20R-8057 10R-4761 for E324D E325D E329D Excavator Nozzle original new injector

Engineered for demanding diesel service, the 20R-8057 remanufactured fuel injector is a direct OE-matched replacement for C7 and C7 ACERT engine platforms used across medium-duty trucks, buses, excavators, wheel loaders, generator sets, and a wide range of industrial and off-highway machinery. Each unit is rebuilt to restore precision fuel delivery, consistent atomization, and stable cylinder-to-cylinder output, supporting the performance and durability expected in professional fleet and rebuild environments.

This injector cross-references a comprehensive range of legacy and current part numbers, including 20R8057, 10R-4761, 222-5961, 222-5959, 233-3536, 236-0973, 241-3238, 243-4502, 295-1408, 328-2583, 387-9430, 293-1408, and EX634761, simplifying sourcing for distributors and repair shops. Remanufactured using specialized metallurgy and updated manufacturing processes, each injector incorporates critical engineering updates and is developed for today's low-sulfur, low-lubricity diesel fuels. Extensive functional testing verifies flow rate, spray pattern, response time, and sealing integrity before release, ensuring dependable performance in six-cylinder C7 applications where balanced injector output is essential.

To protect injector service life, buyers are advised to maintain clean fuel supply through regular filter replacement, water separator draining, and tank cleanliness, alongside routine oil and air filter service. Common symptoms addressed by replacement include hard starting, rough idle, misfire, white or black smoke, low power, elevated fuel consumption, and check engine faults. Ideal for fleet operators, parts distributors, engine rebuild workshops, and industrial equipment owners.
