So I am thinking of ordering the Westach combo gauge and mounting it in the SRT 10 Pillar. How easy is this gauge to see in the light and how about the dark? Does anyone wish they would of gone to single gauges in the pillar instead of the combo? I have a 2004. 5 and don't really think I need a Fuel Pressure gauge, so the combo gauge would work well for me. How long does the install take?
