A statement that all the pumps will physically bolt on. But there are differences in the clocking, and depending on the year and application, differences in the check valves.
All my pumps are in a box that is currently not accessible (had to store half the basement on one side to put a Christmas train platform up for one of mygarnd boys, lol), otherwise I would have posted a couple of photos showing some of the clicking differences and valve size differences.
