Under hood fuel filter housing leak

[TRAMPLINEMAN]

My ‘14 has started leaking fuel from the electrical harness connector on the firewall side of the filter housing. It’s dripping out of the light blue connector. Any idea how to fix this?

@TRAMPLINEMAN , Looks like you've got a o-ring that's leaking.

This shows water sensor with o-ring. It appears to be wicking out and onto harness. Got service manual if you need any other help since mine is a '14 3500 DRW. Good luck.

I've not laid hands and eyes on that connector personally, but from the picture, it looks like the green seal (at least it looks like a seal) is twisted up and not inserted properly. Again, I may be totally misinterpreting how those components really are.

It could be leaking through the sensor itself into the wires. So @TRAMPLINEMAN the entire sensor needs to be replaced.

Rare, but, leaks through wires is not unheard of. GM had coolant sensors ruining ECM's back in the '80's from coolant wicking up the wire and corroding the board. I had a frame mounted lift pump connector leaking diesel myself.

Apparently there was a recall on this back in ‘14, but, my truck was built a month after the cutoff date so they won’t cover it. Anyway, none of the dealers around me has the parts to fix it, so I ordered the parts off line.
Thanks for the replies!
