How Important is a COCKPIT fuel pressure gauge?

I'll have to check, I don't remember the exact numbers off the top of my head??

Fuel pressure is the pressure of the fuel in the rail and/or supply line (the line between the pump and the fuel rail, where the fuel filter is).

Measuring fuel pressure in the return line would be like measuring oil pressure in the turbo oil drain tube. What's the point? It's a drain tube. The fuel return line is just a drain tube back to the tank.

So why do companies put NPT ports right on their regulators for guages. Mine is screwed right on to my Aeromotive. Is this not good then?

I would be inclined to belive that a gauge mounted directly on the FPR like the aeromotive would give you an accurate reading of the fuel pressure in the rail. Mounting the gauge after the FPR on the return line is where it would be pointless to have it.
