iv heard that automatic trans fluid is goo to mix in deisel(or run in place of deisel if you can get it for free), just passing it on, i actually didnt know what a fuel bowl was on an f350, all i run into on a dail basis is mercades 3.0 5 cyl deisels,
Do not run modern ATF in diesel......... it's made to be non-flammable (not saying it won't burn, but you wont get the complete burn you need)
