Good info on the pre ULSD rubber hoses and upgrades. The gaskets in lift pump for our 2004 Dutch Star started leaking most likely from a reaction with this fuel.
The ECM change to 400HP config was about $450.
Optilube XPD (Several version depending upon winter vs summer blends.) is a popular one. Staydyne, Howes, Lucas, and even Cummins and CAT now have additives also available. And many more, Amsoil has products too. On my droid and heading into a movie or I'd search for you. Do a search on Diesel Additives and you'll find lots of reading material
