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.
