FUEL LEVEL SENSOR UNIT, FUEL FILTER AND FUEL PUMP ASSEMBLY

CAUTION:

Quick connector can be disconnected when the tabs
are completely depressed. Do not twist it more than
necessary.

Do not use any tools to disconnected quick connector.

Keep resin tube away from heat. Be especially careful
when welding near the resin tube.

Prevent acid liquid such as battery electrolyte, etc.
from getting on resin tube.

Do not bend or twist resin tube during installation and
disconnection.

Do not remove the remaining retainer on hard tube (or
the equivalent) except when resin tube or retainer is
replaced.

When resin tube or hard tube (or the equivalent) is
replaced, also replace retainer with new one.

Replace same color retainer as before replacing.

To keep the connecting portion clean and to avoid
damage and foreign materials, cover them completely
with plastic bags or something similar.
8. Using fuel tank lock ring wrench (commercial service tool),
remove lock ring.
9. Remove fuel level sensor unit, fuel filter and fuel pump assem-
bly.
CAUTION:

Do not bend float arm during removal.

Avoid polluting the inside by residue fuel. Draw out with
avoiding inclination by supporting with a cloth.

Avoid impacts such as falling when handling compo-
nents.Retainer color: White
