Default Meziere pump question

How can I tell if I have the HD unit or standard one? I purchased the pump from a forum member 3 or 4 years ago and dont have any papers with it.

OK, mine measures 2.5 inches for the case. But if you include the dimple where the shaft rides, its 2.75 inches. Do you think that is the standard or HD? And thanks for your help.

Ok, thanks for your help!! The reason I was asking is Im considering a supercharger and was told that the std pump would barely clear the discharge tube but the hd pump would hit.
