Field wiring connections of the Vac Sensor components <br /> are sealed in a customer supplied containment sumpiunction box(JB). <br /> Seal off STP <br /> Barbed fitting in siphon <br /> port for vacuum source <br /> To console F- <br /> Product line <br /> Dual weatherproof junction vacuum fitting <br /> boxes w/cord grip wiring <br /> entries containing epoxy <br /> sealed connections <br /> Double wall sump ............... ....... ..................
