How to measure fuel pressure

[mookieit]

I would like to measure the fuel pressure on a 2015 s550.

I am imagining I can install a permanent gauge or connector at the fuel rails but I am having trouble finding something easy to install.

What would be great is a device that can send live data to my phone so I can monitor

Please share you thoughts on how could i tackle this

You will need a fuel pressure test kit, and the correct adapter to intercept the fuel feed line where it transitions from the hard line at the firewall, to the flexible line feeding the rails.

Do the fuel rails on the V6 have a schrader valve on them?
