Were can you get injector washers around town, and if not where do you order them from. And how much does a smaller or larger washer effect your spray pattern?

 

Cummins dealer or a fuel injection shop.

 

It's not so much the spray pattern that they affect.

Without them, the injector sits a little too far down in the hole. Thus, possible piston-to-injector contact.

Not to mention that the injector crossover tube won't seat in the injector properly, and you will have an internal fuel leak.

Not to mention that the injector won't seal to the chamber without them, and you will have ALL kinds of problems.

Don't even THINK about installing injectors without them. Also, make sure that the OLD washer comes out with the old injector. "One washer-- one washer only please, Vasili."
