1. Remove the fuel pump flange and inspect the inside of the fuel tank for fuel. If no fuel is present, please
continue with the procedure outlined below.
2. Install a fuel-resistant cable tie around the suction jet pump supply (green) and the vent (red) lines. When the
cable tie is installed, there should be a gap of no more than 5mm between the two internal lines (Figure 2).
Note: DO NOT bundle the blue line into the cable tie with the suction jet pump supply and vent lines.
