5. Check the entire cooling system for leakage.
6. Install the right-side seat-base; then install the cen-
ter console and seats making sure the seats lock
securely.
Electric
Fuel Pump/Fuel Level
Sensor
(550/700 cc)
The electric fuel pump and fuel level sensor are not
serviceable components. If either component fails, it
must be replaced.
TESTING
1. Turn the ignition switch ON and listen for a
momentary “whirring” sound of the pump build-
ing pressure. If the sound is heard (10 seconds), no
electrical checks are necessary. Turn the ignition
switch OFF.
2. Disconnect the gasline hose from the fuel rail; then
install a suitable pressure gauge.
FI092A
3. Turn the ignition switch to the ON position. The
fuel pressure should build until the pump shuts off.
Pressure should read 3.0 kg-cm
2
(43 psi).
4. If the pump is not running, disconnect the fuel
pump/sensor connector by reaching under the rear
rack from behind.
5. Connect a multimeter to the power supply leads
with the red tester lead to the red wire and the
black tester lead to the black wire; then turn the
ignition switch to the ON position. The meter
should read battery voltage. If battery voltage is
indicated and the fuel pump does not run, replace
the pump assembly. If no battery voltage is indi-
cated, check the ECU and the vehicle tilt sensor.
REMOVING
1. Remove the key from the ignition switch.
2. Remove the seats, center console, and right-side
seat-base; then disconnect the negative battery
cable.
3. Disconnect the electrical plug from the main har-
ness; then disconnect the gasline hose from the
fuel pump.
4. Mark the fuel pump mounting and gas tank for
installing purposes; then remove the screws secur-
ing the fuel pump to the gas tank and remove the
fuel pump.
5. Using duct tape or other suitable means, cover the
fuel pump opening.
! CAUTION
After operating the vehicle for the initial 5-10 min-
utes, stop the engine, allow the engine to cool down,
and check the coolant level. Add coolant as neces-
sary.
! WARNING
Whenever any maintenance or inspection is made
on the fuel system during which there may be fuel
leakage, there should be no welding, smoking, open
flames, etc., in the area.
AT THIS POINT
Prior to removing the electric fuel pump, the follow-
ing check should be performed to determine that
removal is necessary.
! WARNING
Gasoline may be under pressure. Place an absor-
bant towel under the connector to absorb any gaso-
line spray when disconnecting.
! WARNING
Always ensure that power cannot be inadvertently
applied to the ignition/ECU when working on the fuel
system. If the ignition switch is turned on, the elec-
tric fuel pump will start and gas could be rapidly
pumped and spilled resulting in fire and severe
injury.
! CAUTION
Take care not to damage the float or float arm or
replacement of the entire assembly will be necessary.
