I have a piston pump on my pickup, and am looking at getting another Westach fuel pressure gauge (another, as in "I had one on my last pickup, and I'd like another one on this truck"). I recall Philip saying that most electric gauges like to be in the middle of their range. Since the psiton pump typically puts out 15-16psi, that leads me to believe that I need the 30psi, but would it be overkill?
