INSPECTING THE PRESSURE REGULATOR Inspect: • Pressure regulator Faulty → Replace the pressure regulator. Inspecting steps (1) Install the fuel pressure gauge onto the pressure check valve and then install the Mity vac onto the pressure regulator vacuum hose. Fuel pressure gauge ................. 1 YB-06766 / 90890-06766 Mity vac ..................................... 2 YB-35956 / 90890-06756 (2) Start the engine. (3) Apply vacuum pressure with the Mity vac.

Vacuum pressure Approx. 25 kPa (0.25 kg/cm2, 3.56 psi) (4) Inspect the fuel pressure. NOTE: Make sure the fuel pressure in the highpressure fuel line lowers conversely in relation to the amount of pressure that is applied to the pressure regulator.
