I have an 04 GT. And i want to install an Autometer Pro Comp Electrical fuel Pressure guage and a mechanical Vacuum/Boost Gauge. Only one problem, apparently on the 04's there is no schrader valve on the fuel rail. so how am i supposed to hook this thing up? also where on earth am i supposed tohook up this boost gauge? nobody seems able or willing to help, i have exhausted all possible local resources. If anybody has come across a similar problem, i would really love some help, and it will be greatly appreciated. The gauges are for a Vortech SQ S-Trim. Both are Autmoeter Pro Comps. Thanks.
