I use something similar to this at work: Car Fuel Injector Cleaner Tool,Non-Dismantle Fuel Injector Cleaner Kit with 600ML Tank,140PSI Fuel Injector System Cleaning Machine with Portable Case For Petrol Cars https://a.co/d/adtUZIu

Keep in mind you will need to disable the fuel pump by pulling the fuse, tap into the fuel rail, plug the fuel rail return line, and then run fuel injector cleaner designed to be ran through the fuel rail directly while the engine is running. We use MOC fuel injector cleaner kits at my work (gm dealership).

It’s worth pointing out that fuel injector cleaners usually only cover the cost of the cleaner if an injector fails during or after cleaning (it’s happened to me and possible) and that you are only cleaning the internals that touch fuel. It will not fix a bad fuel injector solenoid/driver. If the fuel injector is too clogged then the cleaner can’t flow to clear the blockage either.

Considering our fuel system I would recommend using fuel injector cleaner additive that gets added to the tank vs using a fuel injector cleaner tool at the fuel rail. Newer vehicles are manufactured with fittings on or right before the fuel rails which make it a lot easier to use the fuel injector cleaner tool.
