Cummins 4903319PX Remanufactured Celect EUI Fuel Injector — remanufactured electronic unit injector for Cummins N14 engines, sold on a premium exchange basis. Each unit is fully disassembled, cleaned, rebuilt with new wear components, and flow-tested to Cummins specification before shipping.
N14 Injector Symptoms
On a Celect-equipped N14, each injector meters fuel and controls injection timing at the cylinder. As internal components wear, delivery volume and spray pattern drift — and because there's no central pump correcting for it, one worn unit changes how the whole engine runs. Common signs include rough or unstable idle, hard starting when cold, white smoke on startup, black smoke under load, reduced power on grades, rising fuel consumption, and cylinder-specific fault codes. Many operators replace injectors as a set once mileage is high, since remaining units are usually at similar wear.
Remanufacturing Process
- Full teardown — every core disassembled and ultrasonically cleaned
- New wear components — plungers, barrels, springs, and seals replaced
- Dimensional inspection — internal surfaces measured against OE tolerance
- Flow and spray testing — calibrated on Cummins-specification equipment
- Individual verification — each injector tested before it ships
Applications
Cummins N14 engines with the Celect fuel system. The N14 was used across Class 8 highway tractors, vocational and heavy haul trucks, and a range of industrial applications.
Confirm Celect vs. Celect Plus before ordering. The N14 was built with both fuel systems, and their injectors are not interchangeable. Check your engine serial number and current injector part number against this listing before purchase. If you're unsure which system your engine has, contact us with your ESN and we'll confirm the correct unit.
Premium Exchange & Core Return
This injector is sold as a Cummins premium exchange unit. A core charge is added at checkout and refunded when your rebuildable core is returned. Cores must be complete, with no cracked or damaged bodies, to qualify for refund.
