Hi all after some help please, I've got a AGU and have seen many people have fitted Saab red injectors, well I have also purchased Saab reds and after having them given the all clear I decided to fit them tonight into my manifold. They fitted fine in the fuel rail, but when I came to fit it into my manifold I came across a problem, they are to big, so I removed the large allen key holder situated in the manifold and re-tried again, with no joy. Basically what I would like to know is, what is the trick? Is there something else that I need to buy for them to fit? Any help will be greatly appreciated.
