Fuel Pressure Inspection
Be sure the battery is fully charged.
Remove the fuel 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
Fuel is flammable and explosive under certain con-
ditions and can cause severe burns. Be prepared
for fuel spillage; any spilled fuel must be completely
wiped up immediately. When the fuel hose is dis-
connected, 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
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

Fuel is extremely flammable and can be explosive
under certain conditions resulting in serious injury
or death. Do not try to start the engine with the fuel
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.
