Failure to follow these instructions may
result in personal injury.
CAUTIONS:
23m &AUTION:M~~~ sure that the float or
arm are not damaged while removing or
installing the fuel level sensor.
Remove the fuel level sensor.
1. Remove the locking ring.
2. Remove the O-ring seal.
Discard the O-ring seal.
3. Lift the sensor from the fuel tank. Make
sure the fuel lines are connected in
the correct fuel-flow direction. Fuel supply
line connectors are white or are identified
by a white band. Fuel return line
connectors are red or are identified by a
red band.
A Make sure that the fuel supply and fuel
return lines click into place when installing
the lines. To make sure that the fuel lines
are fully seated, pull on the lines.
N0TE:lnstall a new O-ring seal.
N0TE:When installing the fuel tank make sure the
fuel lines do not get kinked or trapped.
N0TE:lnstall new fuel filler and vent pipe retaining
clamps.
