DC8-62 spec flaw range vs. fuel flow

Compare the data of the different engines:

All data except for the fuel flow per hour is identical.   As payload and MTOW are identical I suppose the fuel capacity should be too, thus resulting in a better range for the -7 engined version.   I doubt that Douglas reduced the fuel capacity leaving potential payload open :-)
