Built to support reliable fuel delivery in demanding Caterpillar heavy-duty diesel operating environments, the 359-4050 is an original CAT common rail fuel injector group, also searchable as 3594050. It is engineered for integration into Caterpillar fuel injection systems, with 20R-1308 (20R1308) verified as the related Cat Reman mechanical electronic fuel injector part number for the same component family.
Public parts databases and supplier listings associate the injector with CAT C15, C18, C27, C32 and C32 Marine engine families, as well as a wide range of heavy equipment including mining trucks, dozers, wheel loaders, marine vessels, generator sets, expanded mining and petroleum products. Additional supplier-reported cross numbers support search and matching across global B2B procurement channels, though these references may group related injector families rather than direct one-to-one replacements.
CAT-engineered design benefits include coated plunger wear resistance, optimized service wear life, fuel economy support, and compatibility with low-sulfur diesel fuels, with all units subjected to rigorous testing to meet original equipment performance requirements. Buyers must confirm fitment via the engine serial number, engine arrangement number and original injector part tag before ordering to eliminate compatibility risks.
