I want to install a fuel pressure gauge inside my bezel, but don't know if anyone has done it? I have seen boosted engines witn one right off of the fuel rail, but how much harder would it be to run it inside the firewall and hook it up?
That's what I thought but Autometer says that you should use an isolator so that there is no actual gas in the cabin. Don't know what that is and the website doesn't show it.
