original 162-0218 HEUI Fuel Injector for 3126 C3126 Engine 322C 325C Excavator 1620218 10R-9238 0R-9349 131-7150 178-0199 Diesel Parts original new injector

Engineered as a direct original-type replacement for the 3126 engine family, this HEUI diesel fuel injector (OE 162-0218, cross references 0R-8633, 135-2581, CA162-0218, CA0R-8633, CA135-2581) is purpose-built for the 7.2-liter inline six-cylinder turbocharged diesel platform. The 3126, 3126B and 3126E engines rely on Hydraulic Electronic Unit Injector technology, using high-pressure engine oil as the actuation medium while the ECM precisely governs injection timing and duration. This injector assembly is manufactured to industrial heavy-duty standards for fleet-level durability and consistent hydraulic response.

Key performance advantages include accurate fuel metering, stable spray atomization, improved cold starting, refined warm-up behavior, controlled emissions, better fuel economy and stronger throttle response. The unit is designed for a wide service footprint: medium-duty and vocational trucks, dump trucks, buses, RVs, marine propulsion, standby generators, emergency and municipal fleets, and construction machinery. Documented brand compatibility includes Freightliner, Ford, GM, International, Kenworth and Peterbilt 3126-powered platforms, making this injector a strategic SKU for professional repair shops, diesel injector distributors, engine rebuilders and heavy equipment parts sellers.

Before installation, confirm engine serial number, injector part number and original configuration; install new seals, inspect wiring, prime the fuel system and run diagnostic checks. Since HEUI systems are sensitive to fuel contamination, oil contamination and low actuation pressure, maintain clean diesel fuel, timely filter replacement and clean engine oil to maximize injector service life.
