I was pulling injectors on my truck and in the process managed to crack/break the top plastic part on one of them right where the plug attaches to it. I have stage 2 single shot 160cc from Rosewood Diesel. What needs to be done to fix it? Can I just put silicone over the crack to seal any oil from getting down in? Can I get a top piece off of a stock injector and just swap them out? Or is it a main part that has to do with the injector flowing more fuel and being single shot and I'd have to send it back to Rosewood to have them fix it right? I'm really not sure and would appreciate any responses for help. Thank you
