Notice how it has a FMC360 case number section? That means only someone with access to FMC360 like a service manager, has to file one of those first. So you have to get the SM on board before you can do anything. It's as if Ford doesn't wan't to receive any of these?

There is a warranty cancellation request form you can search for on FMC, and you can select just the fuel system as an option if I remember correctly. Of course it will end up in a phone call to your dealer from some Ford rep who will simply tell you that unless YOU can PROVE that gasoline actually caused damage, that it has to be covered. So then you will perform a repair, only to have it get kicked because the aforementioned Ford rep will not give you a prior approval code, or be there to get the claim paid once kicked. Moral of the story is just send an email to hotline and let them decide what to do.

We had one this week.

Isn't TA-357 what they used from the factory? If it is, I'm not impressed.

TA-31 doesn't ever seem to become hard and start leaking like all of the black silicone variants seem to do after a few years. The only time I've ever had to do a factory installed 7.3 oil pan, was because the pans themselves rusted out. With properly prepared surfaces, TA-31 is a lifetime silicone in my opinion. The engineers aren't just afraid of O2 sensor contamination though, they seem to have a fear of oil foaming. I'm less fearful of such things... Perhaps when they can build a half decent door latch I'll start to care what they think.

I use it for everything and haven't had any problems with contaminated O2 sensors. But even if I had to replace the occasional O2 sensor it would still be worth it.

Oh good, its probably one of those things that wouldn't act up if it had more than half a tank, but drop below that and she starts sucking air through the side of the tube where the orange thing used to be. Got to love used cars.

I hate to ruin the celebration, but it's possible you have found another symptom and not the cause... The only times I've ever seen the orange valve fall out was when the system had gasoline contamination. Granted it may have been done quite a while ago, but it puts in to question the integrity of the entire fuel system.

^ You mean AB injectors right?

Found this info posted by RT at The Diesel Stop:

STC fitting might have a tiny leak, not enough to cause problems under pressure yet, but maybe enough of an air leak for an issue if it sits long enough.

Me too, that way I can blame the pharmacist (parts guy) if that doesn't solve the problem

I agree with checking both ends of the track bar for any play as a first step. Often times I will get this concern as a comeback after someone has already done the track bar and alignment fix to no avail. When that happens, I will make sure nothing else is loose before prescribing new front shocks and the Rancho dual steering stabilizer kit, which our local Napa keeps in stock. I realize that as a dealer tech, relying on an aftermarket fix doesn't quite feel right, but it has always worked for me. And these truck drive so much nicer after that kit is installed.

I use petroleum jelly liberally and never had a problem. My high school shop teacher, Mr. Frye always said: "Nothin goes together dry or dirty, if you don't learn it in my class you'll learn it in health." I wonder what he meant by that
