Somewhere the plans show you drilling a hole in that valve cover and using a bushing just like you do through all the bulkheads farther aft. Not a big deal. I then cut a notch up to the hole in the cover so that I could completely pull the cover off whenever needed, even if the trim cable is permanently installed.How did you route the manual trim cable past the F983C fuel valve cover in a non fuel injected set up. I can't find anything in the plans that shows that part of the routing.
