OM642 Fuel injector puller
Which puller you guys use to remove fuel injector on OM642?
I found this set, but description doesn't mentioned OM642.

Do I need any other special tools to remove injectors?

How do you know you need a puller? Do you have black death?
Clean injectors will come with hand pull and if they are slightly stuck, small twist within the holder movement will free it.

I have leak and I need to replace washer. I don't have black death yet. I want to be prepared just in case I will have difficulty to remove it. For the fuel line do I need special 17mm socket or crowfoot wrench will work as well?

I would not do it that way. You pull the screw too much out and you risk the treads in the head. Never mind if this injector hits your head....
Reminds me of my early days of bleeding brakes on my dad's car with the motor running. Lol
As you probably guessed it, the bleeder screw flew out of the caliper stripping the threads. Lol forgot about that. In case you're wondering why, I thought this would expedite the process.

Brakes bleeder has just few threads and operates with thousands of psi, when injector bolt has lot of threads. I heard that turning the bolt 1 turn and taking the car for a drive will break black death.
Again, no situations are equal. Chances are the injector will come easy. Main issue is to pull it on hot engine.
