Fuel leaking from ECM

I was running with upper part of the wire loom wrapped in paper towel and plastic film to figure out is fuel coming from inside the loom or it's sprayed from outside. Wasn't sure 100% with the test results. Ended to reattach wires so it has downloop before ECM to keep fuel away from the plugs. it's dripping down before.

Yea, I had actually considered the same ...rather than waste the money on a new sensor. When you look at that sensor on mine, it def has fuel dribbling through. With the camera you could actually see the droplets hanging from the terminals.

I cleaned out the ecm plugs and wiped the harness, but I'm thinking the damn fuel that's in there in just gonna be a pain to get rid of entirely...even with the leak being fixed, there's plenty of places for it to hang around (such as within every damn ridge of the loom!)

I may end up cutting the loom off and replacing once the new sensor comes in. It would be a real PITA, but at least I'd have a clean slate to start from.
