Went to my local Cummins dealer yesterday for filters for my 01 because of the ever changing pricing from Dodge. I gave Cummins my #s LF3894 and FS19579 which they said had been superceded by LF3935 and FS1261,I have not installed these yet because I think they are wrong, anybody know if these are ok or not, I know the oil filter will fit but I believe this is an old #. Thanks for any help.
