Need help

Have a 1990 ford f250 7.3 idi. Changed the injectors out yesterday and have 2 or maybe 3 that are sucking air around the injectors or blowing bubbles if sucking wasn' t right term to use. I tried tightening more but was tight as I could get any ideas on what the problem could be.

did you put the new copper washers under the new injectors?
sounds like you used to old ones, or did not put the washers back under the injector.

I put new washers under the injectors and even re check myself and made sure the old ones were off, by looking at all old injectors and they were still stuck to old one.
