I have a mechanical fuel pressure gauge on my truck and have it hooked up al the time, I cant figure out how to keep the anti freeze in the tubing from the isolater but its perfectly safe to keep it hooked up. I have the issopro gauges got the whole set for less than 300$ egt, boost and fuel. The one that you shouldn't keep hooked up all the time is the fuel psi test gauge that most people buy and hook into the stock fuel line just to test the pressure then remove.
