did diesel pumps have a larger diameter hose and/or nozzle than gasoline pumps had?

i picked up a nice, N.O.S. brass nozzle, cheap, that was apparently meant for a diesel pump, and the inside diameter of the fitting is slightly larger than one and a half inches. i don't have a hose on my M & S 80, but i assume a one inch hose would not fit(?)
if not, is there a reducer fitting available to marry these two sizes together? i can do the research on the fitting, but i thought i'd ask while i'm asking my other question.
if not, i think i will be posting a nice, N.O.S. brass nozzle, cheap, in the classifieds section, ha aha.

thank you in advance,
