I am hoping someone can answer this question for me. I am replacing all the rubber hoses on a 1989 mercury 90HP 3 cylinder and when I was doing this the plastic fittings turned slightly while putting on the new hoses on the induction manifold. They appear to have thread sealant on them but are plastic and weren't that tight. There were also no clamps on the hoses. I am wondering by disturbing them if I now need to disassemble and reseal with thread tape or some sort of sealant? If I do what is the best sealant to use and how do you get the fittings to stay in the correct orientation since they are plastic its not like you can put any pressure on them to get them tight without damaging them. Should I be replacing them with brass? Sorry if this is a dumb question but since its beyond the throttle plate I am worried it might lean the engine out if it draws air. I attached a picture so hopefully it is more clear.
