Was wondering about a manual gauge to read the fuel pressure, as interested to do some testing/learn a bit more about this.
If I get a fuel pressure tester with a schrader valve attachment, does this attach onto the valve on the hpfp?
By attaching to this point, does it only read the low pressure fuel pressure regardless of if the engine is on or off? Or does it read the high pressure (which I imagine is too high for a standard gauge)?
