Just picked this up. Any reason this won't work?

That ought to work. I’ve been using this.

Real-Tuff 15605 PTFE Paste Thread Sealant https://www.amazon.com/dp/B005IOKDB4/ref=cm_sw_r_cp_api_r25EAbKE0CFND

I bought it at Depot I think. Seems to be doing fine.

that will work fine

Cool. I'm hoping to work on my f350 Friday, tomorrow is spoken for. I have to replace the radiator in my Freightliner. It's pretty much a full day

Anyone know what this is?

Filter restriction sensor. Turns on the change filter light.

Ok.

I don't have a change filter light, unless that sensor can control the water in fuel light also.

Okay technically it's just "fuel filter." You do have one somewhere.

What year is your truck? If you have this wire then you have a dash light indicating you need to change the fuel filter. I have only seen my filter light come on once. Even then it slowly illuminated under full hard throttle. The way this switch works is it measures a vacuum in the fuel delivery to the injection pump.

Ok, thanks for the info. I guess I should be glad it has never lit up

Just ground that wire as a test. Bulb may be out. Lol

I replaced all my dash lights with LEDs, I'm pretty sure the bulb is good. When I fix the leak, I'll ground that wire with the key on and make sure a light lites up somewhere.

Thanks again guys for the help

Lol The led could be the issue....

I checked them all in a spot that lit up with the headlights before putting them in the current spots. I wanted to make sure the polarity was correct.

That doesn't mean anything for the warning lights.....
