The DieselManor Fuel Pressure Gauge Isolator is used for isolating the fuel pressure gauge from the fuel source.  This prevents the possibility a fuel leak inside the passenger compartment.  The isolator is to be mounted under the hood.  It is connected to the fuel source via S.S. braided fuel line and to the fuel pressure gauge via pressure tubing kit*. DieselManor strongly discourages the use of any mechanical fuel pressure gauge without the use of an isolator. The isolator comes complete with stainless steel mounting bracket, mounting screws, adapter fittings for 1/8"NPT connections, firewall grommet, and instructions.
*S.S. braided hose and tubing kit not included.
