Proven Reliability for Your Caterpillar Fleet The 4P-9830 fuel injector is a cornerstone of the fuel system for CAT's most reliable workhorse engines.

Our 4P-9830 injectors are manufactured to meet original Caterpillar performance standards. We focus on the internal needle and seat geometry—the parts most critical for preventing leaks and maintaining precise injection pressure.
