Fuel pressure gauge install

[Bigsmoothe49]

2003 6.0, where is the best place to tap into the fuel system to add a fuel pressure gauge? I want to install a sender for an analog gauge. I have seen on the web a billet cap for the secondary fuel filter housing with a threaded hole in the top for gauge fitment. Is this location in the cap adequate?

There is a test port on the Sec/top fuel filter that you can use. I don't have one but thought about it. good luck
