Wouldn't it be the vacuum between the check valve ball in the racor and the injection pump - a big part of the system, minus back to the tank?
Probably a better way to address this is that the cause of abnormal vacuum that the gauge is registering, is from the fuel tank(s) to after the Racor filter element. Somewhere between those two points is where a restriction is developing.
