Q: How to Service and Repair a Fuel Injector on 2006 Dodge Ram 2500?
A: To service fuel injectors, pull off the fuel rail and disconnect injector-retaining clips. Install injectors into fuel rail and clip in place. If reusing injectors, install new O-rings on each and lubricate them with a bit of clean engine oil. Reinstall the fuel rail and start the engine and check for fuel leaks.
