Ensure there is enough gas in fuel tank.
Use the VCK (Vehicle Communication Kit) to re-
lease the fuel pressure in the system. Look in the
Activation section of the software B.U.D.S.
Disconnect inlet and outlet hoses from fuel pump
using tool (P/N 529 035 714).
Connect adapters and pressure relief valve to
pressure gauge as shown.
1. Pressure gauge (P/N 529 035 709)
2. T-adapter (P/N 529 035 710)
3. Pressure relief valve (P/N 529 035 711)
CAUTION: Ensure to install the pressure relief
valve to allow excess pressure flowing back
through return line. Note the arrow on the valve.
Otherwise, fuel pump components might be
damaged.
Install pressure gauge between disconnected
hoses on fuel pump side (closed-loop installation

2. Fuel pump return line
3. Fuel relief valve on the return line side
4. Pressure gauge between disconnected hose (inline installation)
Crank engine and observe fuel pressure.
MINIMUM FUEL PUMP PRESSURE
(at cranking)
721 kPa (105 PSI)
If pressure is within limits, fuel pump is working
adequately.
If pressure is below limits, ensure fuel filters are
not obstructed. There is one in-line fuel filter at the
fuel pump outlet hose and one filter at the inlet
underneath the pump. Otherwise, replace the fuel
pump.
Remove pressure gauge and reinstall fuel hoses.
