What is the simplest and safest way to add a fuel pressure gauge? Is there already a port available to tap into or do I need to upgrade either the regulator or fuel rail? Or is there another method that is simple and effective? I plan to install the FP gauge along with Wideband, Oil Pressure, Water Temp, and (maybe) Boost on a 2006 Mustang GT with Roush M90 supercharger. I've searched around and not coming up with any sort of common, simple, method...most of what I've found involves a lot of other mods...seems like this should be relatively straight forward so forgive me if it's a dumb question Appreciate any advice!
