9. CONNECTION OF VAPOR HOSE/8. FILLER HOSE
(1) The vapor hose should be connected all the way at the tank, and approximately 40 mm (1.6 in.) at the fuel tank
filler tube.
(2) The end of the filler hose with the shorter straight pipe
part should be connected at the tank side.
7. CONNECTION OF HIGH PRESSURE HOSE TO FUEL PUMP
Temporarily tighten the flare nut by hand, and then tightenit to the specified torque, being careful that the fuel hose
does not become twisted.
Caution
When tightening flare nut, be careful not to bend or
twist line to prevent damage to fuel pump low connec-
tion.
FUEL PUMP REPLACEMENT
(1) Disconnect the fuel pump connector.
(2) Remove the fuel tank filler tube cap.
(3) Drain the fuel. MllGFAC
(4)
Disconnect the fuel high pressure hose and main pipe.
Caution
Cover the hose connection with rags to prevent splash
of fuel that could be caused by some residual pressure in the
fuel. pipe line.
(5) Loosen the self-locking nuts to the end of the stud bolt.
(6) Disconnect the lateral rod right side body coupling; then lower the lateral rod and use wire or similar material to
suspend from the axle beam.
(7) For models equipped with the ACTIVE-Electronic Control Suspension
(E.C.S.) disconnect the rear height sensor and
the lateral rod. (Refer to GROUP
33B-Service Adjustment
Procedures.)

The front-height sensor detects (by detecting the
