Removal & Installation and Disassembly & Reassembly
1. DISCHARGE FUEL SYSTEM PRESSURE (See page 11-1)
2. DISCONNECT ENGINE WIRE NO. 3 (BATTERY NEGATIVE TERMINAL)
3. REMOVE REAR SEAT CUSHION ASSY (See page 72-39)
4. REMOVE REAR FLOOR SERVICE HOLE COVER
(a) Remove the rear floor service hole cover.
(b) Disconnect the vapor pressure sensor connector.
(c) Disconnect the fuel pump connector.
5. REMOVE FUEL SUCTION W/ PUMP & GAUGE TUBE
ASSY
(a) Remove the tube joint clip, then pull out the fuel pump
tube.
NOTICE:
Check around the connector for dirt or mud before
this operation. Remove the dirt if necessary.
Be careful of mud because the fuel tube joint has an
O-ring which seals the pipe and connector that can
be contaminated.
Do not use any tools in this operation.
Do not bend or twist the nylon tube. Protect the con-
nector by covering it with a vinyl or plastic bag.
When the pipe and connector are stuck, push and pull
the connector to release. Pull the connector carefully.
(b) Remove the 8 bolts, then remove the fuel tank vent tube
set plate.
