Injectors are headed to F1 and I'm trying to round up all the parts i need to install them when they get back. Does anyone know if they put new o-rings on the bodies and include copper washers or should i order them from cummins while i wait?

 

If they are actually working on your injectors, then yes you will get new O-rings. Now I received a set of copper washers with mine, but I think I had to ask for them from the vendor I went through. Just ask, I'm sure with the business you are providing them, a set of washers shouldn't be a problem.

 

Yes they come with new copper washers and o rings.
