- Install Fuel Pressure Gauge (VW 1318) at fuel supply hose 3-way "T" connector. See Fig 1
. Using a jumper wire, connect terminals No. 30 and 87 on fuel pump relay.
- Turn ignition on. With fuel pump operating, minimum pressure should be 33 psi (2.2 kg/cm2
). If fuel pressure is incorrect, inspect for restricted fuel lines, defective fuel pump or weak control pressure regulator. If okay, perform MAIN FUEL PUMP VOLUME CHECK.
