Fuel pressure test valve location

[RedCloud]

I would like to perform a fuel pressure test but am having trouble locating the schrader valve to attach a pressure gauge.

Below is a link to a few photos of what I think may be the correct valve, based on the location of the pipe and where it goes.
One is marked "1" in red and has an "L" on the cap. The other is marked "2" in blue and is marked "H" on the cap.

Let me know if that's correct and which one to use (or both, if so how to use both). If it's not correct, where is the valve to test from?

Thanks.

I found it. It is here: https://drive.google.com/open?id=1jLouPbvY1lkG1Uj72SHJglnFe7EYblOv&disco=AAABwxo_Uw8

Turns out that it isn't as simple as plugging into a schrader valve. You need a setup similar to this one to do it properly. This one is simpler and requires less tools (but may be more prone to leaks).

You know those are aircon service valves, right?

I didn't know that, thanks for clarifying that for me.

This link to a comment highlights where I believe I need to plumb a fuel pressure gauge (ignore the red and blue highlights): https://drive.google.com/open?id=1jLouPbvY1lkG1Uj72SHJglnFe7EYblOv&disco=AAABwxo_Uw8

I don't normally pay much attention to the Gen 8 threads, but are you hoping to measure the injection pressure on an N22B? Before or after the injection pump?

It's an R20 engine and I'm measuring before it enters the engine. Don't know what an injection pump is.

As said here, I've found the test location and I have competed the test.

This video made it far easier.

The next challenge is finding the correct fuel pressure for my engine.
