Perkins original Perkins 4P-2995 Replacement Fuel Injector for 3114/3116 Engine 0R-8682 127-8230 127-8216 Excavator 200B 322B new injector original new injector

The Perkins 4P-2995 diesel fuel injector is engineered as an OE-style replacement for the Perkins 3116 and 3114 MUI engine platforms, with verified fitment for Perkins C7 applications. Designed to match the original mechanical unit injector configuration, it integrates directly into Perkins 3100 Series fuel systems without modification, supporting distributors, fleet operators, and rebuild workshops that require consistent performance and broad cross-reference coverage. Multiple interchange numbers are accepted under the same product line, including 4P-2995, 4P2995, 0R-8471, 0R8471, OR8471, 0R-3389, 0R3389, OR3389, 7E-8952, 7E8952, 0R-3006, 0R3006, OR3006, CA4P2995, CA0R8471, CA0R3389, CA7E8952, 127-8207, 127-8213, 127-8216, 127-8218, 127-8222, 127-8225, and DS-4P-2995, simplifying inventory management across mixed part-number channels.

This injector delivers precision atomization and stable fuel metering to maintain consistent cylinder output under heavy-duty operating conditions. Each unit is tested for leakage, fuel delivery volume, and spray pattern to meet Perkins 3116 performance expectations. The component is suitable for medium-duty trucks, school and commercial buses, marine auxiliary engines, standby and prime power generator sets, construction machinery, and industrial equipment such as compressors, power packs, and material handling units. It is also widely used in the engine rebuild market where matched injector sets are required for balanced remanufacturing.

For reliable operation, clean diesel from a verified source is recommended along with routine fuel filter replacement and frequent draining of the water separator. Common symptoms of a failing injector include hard starting, rough idle, black or white smoke, misfire, low power, elevated fuel consumption, diesel knock, fuel leakage, and excessive exhaust temperature. If cylinder imbalance is detected, all injectors should be tested and replaced as a matched set. Each injector is supplied individually or as a complete 6-piece set, sealed and protected against dust contamination.
