FUEL LEVEL SENSOR UNIT, FUEL FILTER AND FUEL PUMP ASSEMBLY
 Quick connector can be disconnected when the tabs are
completely depressed. Do not twist it more than neces-
sary.
 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.
 To keep the connecting porti on clean and to avoid dam-
age and foreign materials, cover them completely with
plastic bags or something similar.
8. Remove main fuel level sensor unit, fuel filter and fuel pump assembly, and sub fuel level sensor unit as
follows:
CAUTION:
 Do not bend float arm during removal.
 Avoid impacts such as fallin g when handling components.
a. Removal of main fuel level sensor uni t, fuel filter and fuel pump assembly:
i. Remove retainer.
ii. Raise main fuel level sensor unit, fuel filter and fuel pump assembly, and using snap ring pliers, remove fuel hose connec-
tor.
CAUTION:
Be careful not to damage fu el hose connector by expanding
them excessively.
b. Removal of sub fuel level sensor unit:
i. Remove retainer.
ii. Raise and release sub fuel level sensor unit to remove.

 Tighten retainer mounting bolts evenly.
Quick Connector
Connect quick connector as follows:
1. Check the connection for damage or any foreign materials.
2. Align the connector with the tube, then insert the connector straight into the tube until a click sound is
heard.
