ELECTRIC FUEL LEVEL SENSOR
Inspection
All Models except SDI
Visually inspect the condition of connectors and
wiring throughout the circuit. Connections must
be clean and tight, and wiring free of damage. Re-
pair as necessary. Use silicone dielectric grease
to prevent corrosion at the connectors. Operate
theenginetoseeiftheproblemhasbeencorrect-
ed.
A 0.25 ampere fuse protects fuel level sensor cir-
cuitry. Remove seat to gain access.
Torque fuel level sensor retaining screws to 1 Nm
(8 lbfin) in a criss-cross sequence and then to
2.4 Nm(21lbfin), using the same sequence.
SDI Models
Fuel level sensor is integrated to the fuel pump.
Refer to COMPONENT INSPECTION, REPLACE-
MENT AND ADJUSTMENT.
A 0.5 amp. fuse protects fuel level sensor circuity
in fuse box.
FUEL SYSTEM PRESSURIZATION
Fill up fuel tank.
Install on fuel tank, the special cap of leak tester
kit (P/N 529 033 100).
Using vacum/pressure pump kit (P/N 529 021
800), inject air into fuel tank. See next photo.

TYPICAL
1. Special cap on tank
2. Air pump
Pressurize fuel system to 21 kPa (3 PSI). The pres-
sure must not drop during 3 minutes.
If pressure drops, locate fuel leak(s) and repair/
replace leaking component(s).
To ease locating leak(s) at fuel tank vent fitting, fu-
el gauge or fuel cap, spray soapy water on com-
ponents; bubbles will indicate leak location(s).
High Pressure Test (Electric Fuel
Pump Circuit)
SDI Models Only
Install tether cord on DESS post. Push the emer-
gency switch to OFF position. Push on start but-
ton to activate fuel pump.
Check for any leakage at fuel rail, injectors, in-line
fuel filter and fuel hose.
