have been going through the row crop 77 diesel I acquired last yr and have run into a snag with the fuel filter cartridge...I cant find a replacement...1st some background..according to john s. when I sent him pictures he said it was the super style filter canister that's mounted on the side of the engine in front of the starter...I also have a standard 77 diesel bought at the same time from the same guy..it to has the super style filter but it is for the short cartridge...which is what comes up in the books for a super 77 diesel..the filter on the standard that accepts the short filter has fram cast into the top of the unit...the longer unit on the rowcrop tractor does not have fram cast in it...the cartridge that was in it was stamped tractor supply co 2-1454...which crosses to nothing...tractor supply said they havent used filters with their name on them in ages...so all this to see if any of you have run across this before...the filter dimensions are 3" dia by 3 5/8 tall or long with a 1" hole in the center on both ends..any input would be great...thanks for any help
