Almost, but not quite. Thinking about the location of the leak... the #5 injector is directly below the old fuel pressure regulator flange, which I removed and welded the hole. It's possible that the weld is leaking, and more possible that the heat from welding distorted the injector bung so a seal isn't possible. I need to run it long enough to make sure where it's leaking..... then find out why.
