FAQ
Is tuning required after installing this injector?No-this is a stock-flow injector. When replacing a failed stock injector with another stock unit, no tuning is required.
Should I replace connector tubes with injectors?
Yes. Worn connector tubes can cause sealing issues and poor rail pressure. We strongly recommend replacing them at the same time.
Do I need to code the injector to the ECU?
On 2003-2004 5.9L Cummins, individual injector trim codes are not typically programmed like later model years. Follow factory service procedures.
What causes premature injector failure?
Contaminated fuel, low lift-pump pressure, poor filtration, or improper installation can damage injectors. Always address root causes before startup.
Is a core charge required?
Yes, this remanufactured part carries a refundable core charge. Return an acceptable core promptly per instructions to receive credit.
