Wire Identification Help

[FilthyCatfish]

Hey guys I pulled my glow plug harness this afternoon in prep for new plugs. I noticed a broken wire coming connected to passenger side front of the harness. I followed it down and it seems to be attached to the hard line coming off the front of the fuel filter mount somehow. There is a metal sleeve around the hard line and the wire goes up into it. What is this wire? It looks to have been broken for some time. Thanks.

That's the wire for the fuel heater. Not really necessary.

Thanks Wicked. I figured it couldn't be too important since the truck has been running decent. Would it be worth it to just put a new wire in, it can get a little chilly here in WA.

Is this a 6.9?
With today's fuels, you "shouldn't" have to worry about gelling.

I think you can test it using a ohmmeter. If it's good, hook er up.

Today's fuels gel just as bad as yesterdays fuels did.
Hook it up if you want. It certainly doesn't hurt.
