Ford High Sulfur Package
So while going through the new 2015, I noticed that you can get a high sulfur package added, obviously for outside the US or if the EPA gives you permission.

I am just wondering if it's just the emissions components that can't handle the high sulfur. JP8 is very interesting since where I live it's in abundance and a couple of friends have contemplated putting it in, but we aren't quite sure what it would do to the common rail systems. Anybody have any info that it does something different then delete the emissions?

In the USMC we used jp8 with everything. Mostly for generators to heat a building while deployed.
I would not recommend putting it in a new truck. 10 years ago yes but with all the emissions crap we have now heck no.

I guess I was asking if the Ford High Sulfur Package is anything more then deleting the EGR cooler and DPF. It lists the package as 98H, I am just wondering if they put in toughened parts or what.

I don't have any knowledge about the package or what it changes, but I do know that large mining operations have exemptions to use high sulfur fuel in their pickups that don't leave the mining property. Other uses such as military and export to places like Mexico have already been mentioned.
It would be interesting to see what they change. Since the lubricity properties of high sulfur diesel are better than ULSD, I don't see changes to the fuel system being necessary. My guess would be that modified emissions systems are probably what is different.

Interesting indeed. My "guess" it just has to do with emissions also. If so, I wonder if it is a delete or just a change in the components. Maybe similar components with different tolerances and maps.
Did you notice the fine print in the ad? Looks like the package reduces the horsepower...400HP to 300HP but the torque remains the same at 800ft/lb.

Jp8 is diesel. Its just really really dirty. I wouldn't put it in anything unless you plan on spending lots of $ on filters and who knows what else.

I also have several fuel spouts from the Sceptor style fuel tanks that have yellow on the filter from the sulfur, which makes me think that it's just high sulfur diesel. I did see the horse power number lowering. We also had a member on here that bought a truck in Mexico which had this "high sulfur" package installed.

From Wikipedia
When used in highly supercharged diesel engines with the corresponding low compression ratio of about only 14:1 or below, JP-8 causes troubles during cold start and idling due to low compression temperatures and subsequent ignition delay because the cetane index is not specified in MIL-DTL-83133G to 40 or higher. Because lubricity to the BOCLE method is not specified in MIL-DTL-83133G, modern common-rail diesel engines can experience wear problems in high-pressure fuel pumps and injectors. Another problem in diesel engines can be increased wear to exhaust valve seats in the cylinder heads, because a minimum content of sulfur is not specified in MIL-DTL-83133G. Sulfur in fuel normally contributes to a build-up of soot layers on these valve seats. According to the notes in this standard, it is intended to include a cetane index value in one of the next releases.

We have replaced JP8 with F-24. JP8 was never "diesel". I currently have a 1996 K3500 (6.5T) that will not run on F-24. The fuel pump hates it. I discovered that by accident when I filled up with DIESEL at the fuel point. Two minutes after refueling and the problems were solved.

We ate a lot of mechanical fuel pumps using JP8 in our trucks and heavy equipment in Desert Storm. We finally figured out that if we added a 55 gallon drum of straight 40 weight motor oil to our 1,200 gallon tanker before heading to the fuel depot, the return trip with the load of fuel was sufficiently bumpy to mix the oil and JP8, and the oil added the lubricity needed to stop eating fuel pumps.
I also wouldn't put it in our engines.
As far as the high sulfur tune is concerned, I doubt it changed anything with the fuel system, and simply eliminated the emissions equipment that would be poisoned by the sulfur - such as the DOC, and SCR. Since it is an assembly, the DPF would have to be included in the removal.
