I am re-doing a fuel system setup on an F15, it is using a 3 tank setup, and I have a question I am asking for advice on. The two saddle tanks will each have their own vent to the outside, the clunk lines of the saddle tanks will be plumbed directly to their own fitting into the center tank,, I know to keep all lines exact equal length. My question is, where is the best place to put those fittings in the center tank, I believe I have enough room to put 90 degree fittings on the top of the center tank, but if not would it be a problem if I put them on the upper edge of the front of the tank. I have included a rough diagram of what I am talking about, I have always been told they need to be high in the center tank to assure that tank gets completely full before filling the saddle tanks as I fuel the plane. Where is the best place to put those fittings, Advice/Experience is appreciated. thanks
