Note 3: Method of measuring amount of fuel spill flow
The fuel in the spill line is at high temperature (up to 90°C), so be careful not to burn yourself during the
operation.
1) Disconnect the hose connected to the spill tube return collection portion (rear of engine).
2) Connect another hose to the tip of the spill tube, and collect the spill fuel in a container.
3) Start the engine, stall the engine at each speed, and measure the spill fuel amount for 1 minute.
