Unfortunately, it is currently -2 deg C, so I don’t think measuring pressures makes sense for now as we are literally “off the chart” for temperature.

McG,
Return pressure is low pressure, the excess fuel that is sent back to the fuel tank. System pressure is found in the fuel distributor and the line that feeds it, i.e. the fuel filter to distributor line.
You can check system pressure at any temperature, even -2degC. Air leaks have no relation to system pressure as you probably know, best to stay focused for maximum progress and figure out why your system pressure readings are incorrect, be it test equipment or something else.
