I have had this happen to me once and used a similar product as you described from a company by the name of "Racor". They supply alot of diesel fuel products and conditioners to the trucking industry. It worked real well, but it was on a 96' Dodge Cummins 5.9 12 valve engine which is somewhat different than your 2004.

Good luck!
