Looks like you'll have to improvise!
When I used to test fuel pressure, I just used a mechanical oil pressure gauge.

That’s weird, I’ve examined a number of these systems and never seen one without a Schrader valve somewhere on the fuel rail, although they do appear in different areas.
In the absence of that you could undo the fuel inlet pipe and fit in a T piece.

Yep, it’s going to be a tee piece and gauge if I can find out what the thread size is!
