I am considering the purchase of a 1988 BJ74 with the 13B-T engine and had a question regarding the available ULSD fuel in the states. For those who have this engine, have you noticed any increase in fuel pump/injector wear? Do you add any chemicals at fill ups? I work on a ship and we have converted the medium speed four strokes diesel to low sulpher fuel (from heavy fuel) and had to add oil injection lines to help the fuel pumps with lubricity. Thanks in advance! Bob
