So it appears that there are two ways to do this if you still have the FRPS. A guage that goes on the Schrader valve and an adapter that goes on the FRPS then add a guage to that. The 2nd option seems better to me b/c it's further away from the blower heat, and would be easier to read (and look cooler with the hood up). I guess when I go with a Fore system I'll have to use the Schrader location but I don't like it at all to be honest. Does anybody have pictures of their setup?
