Fuel Pressure Inspection
Be sure the battery is fully charged.
Fuel Tank (see Fuel Tank Removal)
Fuel Outlet Hose (see Fuel Hose Replacement in the
Periodic Maintenance chapter)
Be sure to place a piece of cloth around the fuel outlet
pipe of the fuel pump and the delivery pipe of the throttle
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.
Install the fuel pressure gauge adapter [A] and fuel hoses
(Special Tool: 57001-1607) [B] between the fuel outlet
pipe and delivery pipe.
Secure the fuel hoses with the clamps.
Connect the pressure gauge [C] to the fuel pressure
Special Tools - Oil Pressure Gauge, 5 kgf/cm²: 57001-125
Fuel Pressure Gauge Adapter: 57001-1593
Fuel Hose: 57001-1607
Do not try to start the engine with the fuel hoses

Turn the engine stop switch run position.
Turn the ignition switch ON.
The fuel pump should operate for 3 seconds, and then
After turning on the engine stop switch and ignition
switch, inspect the fuel leakage from the connected
portion of the special tools.
Do not drive the fuel pump 3 seconds or more with-
out the fuel in the fuel tank. If the fuel pump is driven
without the fuel, it may be damaged.
Start the engine, and let it idle.
Measure the fuel pressure with the engine idling.
