 NOTE: Inspect the float for any damage or leaking
by submerging in water and looking for any air bub-
bles. Replace if damaged.
4. Install the fuel level sensor assembly onto the fuel
pump assembly housing. Once inserted, press down
to make sure it locks into place.

5. Connect the blue wires using the supplied splice con-
nectors from the fuel level sensor kit. Secure the
wires.
Installing Fuel Pump Assembly
1. Place the fuel pump assembly into the fuel tank with
a new gasket aligning the match marks; then secure
with the cap screws.
NOTE: It is important to install the fuel pump with

the correct orientation to ensure adequate float lever
clearance.
2. Connect the fuel hose and connect the return fuel
hose; then connect the electrical plug to the main
harness.
3. Connect the negative battery cable; then turn the
ignition switch to the ON position and verify that no
fuel leaks are present, the pump runs for several sec-
onds, and the fuel gauge reading is normal.
4. Start the engine to verify proper engine operation;
then shut off the engine and verify there are no leaks.
TILT SENSOR
! WARNING
Incorrect installation of the tilt sensor could cause sud-
den loss of engine power which could result in loss of
vehicle control resulting in injury or death.
CAUTION
Do not drop the tilt sensor as shock can damage the
internal mechanism.
Supply Voltage
1. The tilt sensor (A) is located underneath the battery
access cover behind the battery (B). Disconnect the
three-wire connector from the sensor; then select DC
Voltage on the multimeter and connect the red tester
lead to the orange wire and the black tester lead to
the violet/black wire.

2. Turn the ignition switch to the ON position. The
multimeter should read battery voltage. If battery
voltage is not indicated, check the 20-amp EFI relay,
the 10-amp EFI fuse in the PDM, wiring harness, or
the ignition switch.
3. Remove the red tester lead and connect to the
blue/brown wire. The multimeter should read less
than 0.2 DC volts. If the specified voltage is not
indicated, check wire connections at the ECM or
substitute another ECM to verify the test.
Output Voltage
 NOTE: Needle adapters will be required on the mul-
timeter leads as the following tests are made with the
sensor connected.
1. Connect the three-wire plug to the sensor; then
remove one of the mounting screws securing the sen-
sor.
