The Perkins C7 HEUI Fuel Injector 238-8091 2388091 is a precision-engineered diesel fuel injector designed as an OE-style replacement for the Perkins C7 Series diesel engine. Built to deliver accurate fuel metering, correct injection timing, and consistent atomization, this injector assembly restores balanced cylinder combustion, stabilizes engine performance under load, and supports better cold starting. It is widely used in heavy equipment such as the Perkins 140K2, 324D, 325D, 326D L, 328D LCR, 329D, and M325D MH series, serving engine rebuilders, fleet workshops, and global aftermarket distributors.

Manufactured for heavy-duty operating conditions, the Perkins 238-8091 injector replacement reduces common diesel symptoms including white smoke, black smoke, rough idle, power loss, misfire, and elevated fuel consumption. The unit cross-references with multiple part numbers such as 10R-4763, 20R-8059, 233-3535, 236-0974, 241-3400, 263-8218, 295-1410, 328-2582, 387-9428, 2225958, 2225962, 2313400, 2462343, EX634763, PAI 390093X, Interstate-McBee M-2388091, DIPACO D2388091, and Alliant Power AP63687, ensuring broad recognition across professional diesel repair channels.

Proper maintenance extends injector service life and includes the use of clean diesel fuel, scheduled fuel filter replacement, water separator draining, and routine inspection of electrical harness connectors. Before replacement, technicians should perform diagnostic scanning, cylinder balance testing, and injector leakage checks to confirm root cause. For high-hour engines, replacing injectors as a full set of six is recommended to maintain even combustion and reliable long-term performance in Perkins C7 diesel engine applications.
