If the gears inside the pump were slanted that might be true.
But they are straight cut.
the DRIVE gear.. not the PUMP gears..
the actual pump gears, yea, the pump gears turn the same.
the drive gears and IM shafts turn different directions tho..
There isn't a drive gear on an oil pump.
It's on the vacuum pump.
Side note:
Looks like a gasser I-shaft gear will press off so a gasser I-shaft can work on a diesel,.. with the reversed/diesel gear pressed back on
