Installing Fuel Pressure Gauge

I'm about to install my FP gauge and was wondering, do I have to connect my sending unit to the regulator test port or can I screw it in to the top of my billet fuel cap (which is already tapped). I know that it will screw in there and that's why it was tapped in the first place but I wanted to make sure that putting the sending unit in the cap it would be as accurate as if I would put the sending unit on the regulator. If anyone has any info on this or have compared the pressures at these two different points that would be great. Thanks

I always advise using the test port. It is possible for an air bubble to get trapped under the cap which would make your reading from that inaccurate.

The test port is the brass hex head plug near the regulator

Which way would the reading become inaccurate +/-? Or would the pressure gauge not move because of the air bubble?

I suspect it would flutuate wit pressure changes but read low. Fuel is not compressible but the air bubble will compress.
