If you had 8 bad injectors, I would certainly be installing a fuel pressure gauge. Ford has found that low fuel pressure is the leading cause of injector failures (not including dirty oil causing "stiction" of the spool valves). The minimum fuel pressure is 45 psig at WOT. MANY stock engines (even worse w/ tuners) do not have enough fuel pressure with the OEM fuel pressure regulator spring. The upgraded part is apprx $35 and easy to install.
As far as the leak goes, it could be a glow plug o-ring leaking, CAC (charge air cooler) boots seeping, crank sensor, etc.
