I got a 2003 7.3 that I'm ordering s&b CAI, straight pipe, gauges and chip. Everything injector wise is stock.
Is there a need for the fuel pressure gauge or nah? What would be pro/con of getting or not getting it?
With stock injectors its not needed. Its one of the more useful guages but its not needed. I also sent you a PM. Pro, you can see your fuel pressure con, you can't see your fuel pressure.
