Review on Auto Meter 2173 Autogage Pressure by Angel Serafini

Installed on 97 Jeep TJ with 4.0 on fuel rail. As others have said it doesn't have an equalization valve, it's not that big of a deal as you can just remove the plug which allows it to equalize. It gives accurate readings, but be aware that the rubber plug is easily torn and can fall into the sensor itself (I was expecting there to be a valve under the cover). I was able to fish out the plug, but I snapped it because I had to use a pickaxe to pull it out. I will replace the plug with a high temperature silicone plug.
