Bleeding the fuel system
- Attach a clear plastic hose to the bleed nipple (1) to channel fuel into a
container. The bleed nipple is located at the end of the fuel manifold at
the front of the engine.
- Open the bleed nipple.
- Pump the hand pump (2) until fuel without air bubbles flows out of the
opened bleed nipple.
• If the system is completely empty, it will take approximately
250 strokes.
• After renewing the fuel filter, it will take approximately 170 strokes.
• Approximately 150 strokes are required to bleed the fuel manifold.
- Close the bleed nipple and remove the hose.
- Undo the banjo screw for overflow valve (3) slightly. Pump the hand
pump an additional 20 strokes until the overflow valve opens.
If the engine fails to start after bleeding:
- Open the bleed nipple again and pump the hand pump until fuel
without air bubbles flows out.
- Tighten the bleed nipple. Start the engine and check for leaks.
