If I recall correctly I had to remove the U-shaped runner between the plenum and the stub manifold. BUT, make sure it is the hose, I have had plenty of leaking injectors, that is the body leaking. Do yourself a favor and take some carb cleaner spray and clean it up real good and look very carefully to make sure what is leaking before you tear into it. You will need a new piece of hose whichever it is, and be sure you use the good F.I. rated hose, it's expensive but so are fires from leaks or doing the job again after 6 months.
