3/8 Fuel Line Shutoff Valve Tool J-42964-1 U

The J-42964-1 Adapter Hose connects in the fuel feed line at the filter.   Turning the valve on the adapter allows fuel flow to be restricted for diagnosis of the fuel pump and pressure regulator function.  The Schrader valves on each side of the shut-off valve allow for leak-down check diagnostics and dead-head of the pump for a maximum output pressure check.
