this thread has got me thinking, i have a aftermarket rail, i can move the injectors buy hand when the rail is fitted.

this is my fuel rail



this is the injectors fitted tight against the rail, the seals in the inlet are flush to the top


then i pushed the injector into the manifold


i think i mush have 5mm movement so if the brackets where moved 5mm then they would be no movement, if its ok for the injectors to be pushed into the manifold that far??
