FAQ

Q1: How can I be sure this injector (4948364) fits my specific engine?
A: While this injector is designed for the Cummins 6CT, 6LT, and 6D114 engine families, we recommend verifying your engine’s serial number and comparing it to the OEM parts manual. The most reliable method is to remove your old injector and compare its physical dimensions, nozzle type, and markings to the photos provided. If you are unsure, please contact our support team with your engine model and serial number for verification.

Q2: What is the proper installation procedure for this fuel injector?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Thoroughly cleaning the injector bore in the cylinder head. 2) Replacing the copper washer and O-rings with new ones (sold separately if not included). 3) Torquing the injector hold-down clamp to the manufacturer’s specified setting. 4) Bleeding the fuel system to remove air before starting the engine. Improper installation can lead to injector failure or engine damage.

Q3: What maintenance is required for these injectors?
A: Regularly changing your fuel filters and using clean, high-quality diesel fuel is the best way to extend injector life. If you notice symptoms like rough idling, black smoke, decreased power, or increased fuel consumption, it may indicate a clogged or failing injector. We recommend having injectors tested professionally every 500,000 miles or 10,000 hours of operation, depending on the application.
