Pressure Test Point
On some applications there is a pressure test point with a Schrader fitting in the fuel rail that relieves the fuel pressure and measures the fuel injector supply pressure for repair and diagnostic procedures. Before repairing or diagnosing the fuel system, read any WARNING information. On vehicles not equipped with a Schrader valve, use the Fuel Pressure Test Kit 310-D009 (D95L-7211A) or equivalent with the Fuel Pressure Test Adapter 310-180 or equivalent.
