General Repair Information

Fuel system 

Risk of destroying the fuel pump

After procedures on the fuel system it is possible to damage the fuel pump by running it dry.

-- Never let the fuel pump run dry.

-- Fill or bleed the fuel pump.

• Clean the work area and tools before working on the injection system.
• If the high pressure lines will not be replaced, mark them when removing. The high pressure lines may only be installed again on the same cylinder.
• Align the high pressure lines without tension. First tighten all connections hand-tight and then tighten them again to the tightening specification.
• Never bend the high pressure lines.
