I believe there's value in having tools and test equipment on-hand, especially if they're inexpensive. So I'm thinking about getting a Fuel Pressure Gauge set, but not sure what scenarios it would actually be useful for.
If the fuel pressure sensor on my fuel rail is faulty (happened twice so far), it will send bad signals to the computer which get passed along to the fuel pump. The pump then creates an erratic fuel flow and pressure I can see on my OBD2 reader graph. Adding a manual fuel pressure gauge (connected to the schrader valve on the fuel rail) is not going to give me any additional info.
Are there any use cases where a gauge would be useful?
