Caterpillar 20R-0849 Fuel Injector

20R-0849 Cat Reman Fuel Injector is a rebuilt Caterpillar fuel injector tailored for CAT 3508B–3512B engines, including the 3512B, and is cataloged in the 392-0211 Fuel Injector Group to cover the 3512B family. As part of Cat’s Reman program, this unit is remanufactured to Caterpillar specifications and, like other Cat reman parts, carries a 12‑month parts warranty that matches the coverage of a new injector. The injector precisely meters fuel and delivers it at the right timing into each cylinder, supporting optimized combustion, fuel efficiency, and engine reliability across heavy equipment, marine propulsion, or stationary power applications. Common installations include engines in industrial gensets, construction and mining equipment, and other Cat 3500-series builds, making 20R-0849 a direct fit for 3508B–3512B configurations where refurbished injectors are required.
