For mechanical fuel pressure gauges. Safely isolates fuel source from interior cab. Fuel pressure gauge isolator ensures fuel can not enter the cab even if the tubing or gauge fail completely. The body is constructed of die-cast zinc protected metal with chrome plating and uses a Viton bellows diaphragm to separate the fuel from the gauge fluid. Because this isolator uses a bellows diaphragm it provides 100% isolation while providing a 0.75 cubic inch volume displacement allowing the pressure to transmit through the isolator without effecting gauge readings.

The fuel pressure isolator is designed to be mounted in the engine bay and plumbed between the fuel pressure gauge and the fuel pressue source. The isolators function is to keep dangerous fuel and vapors from inside the passenger compartment of the truck to prevent potential fire and fume hazards. Pure Diesel Power strongly recommends the use of the isolater for any fuel pressure gauge installation that will be inside the passenger compartment of any vehicle.
