Navistar 1819968C91 Fuel Injector Assembly

This fuel injector assembly is engineered for Navistar DT466 and DTA466 7.6L inline-six diesel engines. It utilizes Stanadyne electronic unit injector (EUI) technology, specifically the Model 30410 injector body, providing precise solenoid-controlled fuel metering for direct injection combustion systems. The nozzle assembly corresponds to Stanadyne part number SDLLA142M30411 (nozzle tip 30411), featuring a 142-degree spray angle optimized for the specific combustion bowl geometry of the 7.6L engine platform. The injector operates at high injection pressures typical of heavy-duty EUI systems. This unit replaces Navistar OEM part numbers 1819968C91, 735505C91, and 1819989C1. It is interchangeable with Stanadyne service identifiers 30410 (injector) and 30411 (nozzle), as well as reference code 29498. Available as new aftermarket or remanufactured configurations.
