My csi fuel line started to leak so I decided to replace the injectors and all fuel lines while I was at it. The lines and injectors were original and in need of replacement. I ordered some refurbished injectors from Rockauto that appeared to be identical to the originals. My concern is after installing the new ones with new fuel lines cut to 2.125 in and using the original flanges, the injectors seem to be too loose in their ports. Don't they need to be snug in order to maintain compression? Should they be held firmly in place by the flanges? Am I missing something? The pic attached is of the new injectors and the o-rings/fittings they came with. Thanks for your input.
