Bay Port Bob Posted March 18, 2021 Report Share Posted March 18, 2021 Does any one have a Do it 4oz and 6oz injector? I was wondering if the diameter are the same from the 4oz to the 6oz. I have a Do it duel injector that comes with 4oz injectors and I want to convert them to 6oz. Thank for any help in advance. Quote Link to comment Share on other sites More sharing options...
canuck 2 Posted March 26, 2021 Report Share Posted March 26, 2021 Product info says that the duel system from do it will do both 4 and 6oz injectors. The nozzle o rings fit both sizes. Hope that helps. 1 Quote Link to comment Share on other sites More sharing options...
