I recently found this easy and relatively cheap pressure gauge modification for E61 heat exchanger espresso machines, but was surprised there weren't many YouTube videos that show it in action. It looks like a few retailers sell this part, but I got mine from 1st Line along with a couple copper spacing washers: https://www.1st-line.com/buy/e61-grouphead-manometer-0-16-bar/.

As always, make sure your machine is off, unplugged, and cold when poking around the interior of the machine, and any adjustments are done at your own risk. Safety first!
