rebuilding my 5.9 cummins and like to check see if timing marks are correct?on my fuel pump gear it doesn't have a single "0" or 2 "o,s" has my cam gear and crank gear;;but did see the 2 letters that looks correct to me;;as least common sense tells me this is what I use in place of the 2 "0,s" that my cam gear has;;pics be nice if i'm wrong;;
