That's not a good way to pass the wires through the tank. The wires are pretty much straws, there is a path for the fuel and vapours to comu up through them. You need a proper solution there.
so just to be clear, did anything else change?
you did the coil harness without removing any other component at all? Didn't accidentally unplug other plugs?
That's not really the required metric though? Percentage wise people doing 1000k trips with no stops are incredibly small so not the best to point towards.
