Kawasaki Ninja Service Manual / Fuel System (DFI) / Fuel Line / Fuel Flow Rate Inspection

WARNING

Gasoline is extremely flammable and can be explosive under certain conditions, creating the potential for serious burns. Make sure the area is well-ventilated and free from any source of flame or sparks; this includes any appliance with a pilot light. Do not smoke. Turn the ignition switch OFF.

Be prepared for fuel spillage; any spilled fuel must be completely wiped up immediately.

NOTE

Be sure the battery is fully charged.

Turn the ignition switch to OFF.
Wait until the engine cools down
Prepare a fuel hose (Special Tool: 57001-1607) and a measuring cylinder.

Special Tool - Fuel Hose: 57001-1607

Open the fuel tank cap [A] to lower the pressure in the tank.
Disconnect the primary fuel hose from the fuel pump (see Fuel Tank Removal).

Be sure to place a piece of cloth around the fuel outlet pipe of the fuel pump.

Fuel Line

WARNING

Fuel is flammable and explosive under certain conditions and can cause severe burns. Be prepared for fuel spillage; any spilled fuel must be completely wiped up immediately. When the fuel hose is disconnected, fuel spills out from the hose and the pipe because of residual pressure. Cover the hose connection with a piece of clean cloth to prevent fuel spillage.

Connect the prepared fuel hose [A] to the fuel outlet pipe.
Secure the fuel hose with a clamp.
Insert the fuel hose into the measuring cylinder [B].

WARNING

Wipe off spilled out fuel immediately.

Be sure to hold the measuring cylinder vertical.

Close the fuel tank cap.
Turn the engine stop switch to run position.
Turn the ignition switch to ON.

The fuel pump should operate for 3 seconds, and then should stop.

NOTICE

Do not drive the fuel pump 3 seconds or more without the fuel in the fuel tank. If the fuel pump is driven without the fuel, it may be damaged.

Measure the discharge for 3 seconds.

Repeat this operation several times.

Amount of Fuel Flow Standard: 67 mL (2.3 US oz.) or more for 3 seconds

Turn the ignition switch to OFF.

If the fuel flow is much less than the specified, replace the fuel pump (see Fuel Pump Removal/Installation).
