REMOVAL
CAUTION:
If the fuel gauge indicates that two thirds or more of the fuel is remaining, be sure to drain the fuel before starting the work to avoid the fuel to spill.
1. Fuel spill prevention procedure (Refer to )
3. Draining of fuel (method from fuel tank to filler pipe hose)
(1) If the fuel gauge indicates that two thirds or more of the fuel is remaining, drain the fuel according to the following procedure.
WARNING:
Vehicle components are extremely hot after driving. Be wary of receiving burns from heated parts.
CAUTION:
·Be careful not to spill fuel.
·Fuel may remain in the fuel filler pipe. Drain the fuel from the fuel filler pipe through the fill opening using a gasoline proof pump and gasoline proof hose with a diameter of 10 mm {0.3937 in} or less before starting the work.
(b) Remove the exhaust tail pipe ASSY. (Refer to )
(c) Loosen the hose clamp and disconnect the fuel tank to filler pipe hose.
CAUTION:
·Before starting the work, remove the foreign matters such as dirt on the fuel tank to filler pipe hose connection.
·Be careful not to spill fuel.
(d) Set a metal container under the vehicle and drain the fuel from the fuel tank to filler pipe hose opening using the gasoline proof hose with a diameter of 10 mm {0.3937 in} or less.
CAUTION:
Be careful not to spill fuel.
NOTE:
Always be sure to use a steel container and ground the container as gasoline can easily become charged with static electricity.
(e) Install the fuel tank to filler pipe hose with the hose clamp.

CAUTION:
·Do not use any tools other than the SST.
·Be careful not to damage the tube with the SST.
·Before setting the SST, move the tube to a position outside the SST.
NOTE:
Insert the cutout portion of SST into the rib of ring nut to fix the SST securely.
(3) Remove the ring nut and ring nut plate while holding the fuel pump ASSY by hand.
(4) Disconnect the fuel sub delivery tube and remove the fuel pump ASSY from the fuel tank.
CAUTION:
·When disconnecting the fuel sub delivery tube, do not pull the tube strongly.
·Do not bend the arm of fuel sender gauge ASSY.
·Do not turn the fuel pump ASSY in the fuel tank to prevent the arm of fuel sender gauge ASSY from bending.
·Be careful not to spill the fuel remaining in the fuel pump ASSY outside the fuel tank or in the vehicle.
(5) Remove the gasket from the fuel tank.

(2) Connect the fuel sub delivery tube.
CAUTION:
·When connecting the fuel sub delivery tube, do not pull the tube strongly .
·Do not bend the arm of fuel sender gauge ASSY.
(3) Insert the fuel pump ASSY into the fuel tank and install the new gasket, which was installed to the fuel pump ASSY earlier, to the fuel tank.
CAUTION:
Improper installation such as warpage, slip, etc. results in fuel leakage. Make sure that there is no warpage, slip, etc. in the entire circumference when installing the gasket to the fuel tank.
(6) Install a new ring nut plate and ring nut, and then temporarily tighten the ring nut.
(7) Tighten the ring nut using the SST.
