Engineered as an OE-style replacement for 3116 and 3126 diesel engines, the 10R-8996 fuel injector is a heavy-duty component designed for fleet operators, engine rebuilders, and independent workshops that require dependable fuel delivery. Cross-referenced globally as 10R-8996, 10R8996, 173-4647, and 1734647, this Injector GP-Fuel assembly serves the 3116 inline 6-cylinder, 4-stroke diesel engine platform, featuring 6.6 L / 402 cu in displacement, 105 mm x 127 mm bore and stroke, turbocharged-aftercooled aspiration, and example ratings of 300 bhp and 350 bhp at 2800 rpm.

Built for consistent flow performance and precision fuel metering, the injector supports 3116 truck injector service, 3116 marine fuel injector applications, and industrial engine injector rebuilds. It is widely deployed across medium-duty truck repair, construction machinery service, marine engine maintenance, mining equipment upkeep, generator repair, and diesel engine rebuild programs. Global cross-reference recognition and remanufactured or replacement supply options make it a practical choice for markets in North America, South America, Europe, the Middle East, Africa, Southeast Asia, and Australia.

To maximize service life, replace fuel filters on schedule, use clean diesel, drain the water separator, and avoid mixing injectors with different calibration levels. If symptoms such as hard starting, rough idle, white or black smoke, engine knock, power loss, high fuel consumption, misfire, or elevated exhaust temperature appear, verify fuel pressure, cylinder balance, injector sealing, and calibration before installation in a clean repair environment.
