         Adjust the position of SST (claw set) so that the hole in SST (plate) for installing SST (handle) is in the center of the fuel pump gauge retainer.

      5. 

         *A	for Sedan
         *B	except Sedan
         *1	Fuel Pump Gauge Retainer

         *c	SST (Bolt)
         	Press

         Press SST (claw set) against the rib of the fuel pump gauge retainer and tighten SST (bolt).

   3. While pressing down on the fuel suction tube with pump and gauge assembly, have another person firmly press the fuel pump gauge retainer against the threads of the fuel tank assembly, and tighten the fuel pump gauge retainer by approximately 90°.

      

      *A	for Sedan	*B	except Sedan
      *1	Fuel Pump Gauge Retainer	*2	Fuel Tank Assembly
      *a	SST (Plate)	*b	Tighten approximately 90°
      *c	Fuel pump gauge retainer rises up	*d	Cross Section
      *e	Paint Mark	-	-
      	Press quickly and firmly		Front

      Note:

      • To prevent damage to parts, do not turn SST too vigorously.

      • Do not turn the fuel pump gauge retainer if the paint marks become misaligned.

   4. Quickly and firmly press down on the part of the fuel pump gauge retainer closest to the rear of the vehicle to keep it from rising up.

      Tip:

      • If the fuel pump gauge retainer cannot be properly pressed down due to the position of SST, set SST in a different position.

      • When fully pressing down the fuel pump gauge retainer, there will be a sound or tactile sensation of parts contacting each other, and at this point the fuel suction tube with pump and gauge assembly will stop rising up.

   5. While pressing down on the fuel suction tube with pump and gauge assembly, have another person slowly tighten the fuel pump gauge retainer by approximately 180°.

      

      *A	for Sedan	*B	except Sedan
      *a	SST (Plate)	*b	One Person in Charge of Tightening
      *c	One Person in Charge of Pressing Down	*d	Approximately 180°
      	Front	-	-

   6. Check the tightening status of the fuel pump gauge retainer.

      1. Using a vernier caliper, measure the distance from the fuel tank assembly to the upper surface of the fuel pump gauge retainer at 3 positions as shown in the illustration.

         

         *A	for Sedan	*B	except Sedan
         *1	Fuel Pump Gauge Retainer	*2	Fuel Tank Assembly
         *a	Measurement Position	*b	Vernier Caliper
         	Front	-	-

         Standard

         Difference between the 3 measured values is 3 mm (0.118 in.) or less.

         Note:

         If the difference between measurements is approximately 6 mm (0.236 in.), the threads are cross-threaded by 1 row (6 mm (0.236 in.)), so remove and reinstall the fuel pump gauge retainer.

   7. Install SST (handle) to SST (plate).

      09808-01020

   8. While pressing down on the fuel suction tube with pump and gauge assembly, have another person use SST (handle) to slowly tighten the fuel pump gauge retainer approximately 90°.

      

      *A	for Sedan	*B	except Sedan
      *a	SST (Handle)	*b	SST (Plate)
      *c	One Person in Charge of Tightening	*d	One Person in Charge of Pressing Down
      *e	Approximately 90°	-	-
      	Front	-	-

   9. Slowly tighten the fuel pump gauge retainer until it reaches the fully tightened mark that was copied onto the vehicle body.

      	Tighten		Front

3. CONNECT FUEL TANK MAIN TUBE SUB-ASSEMBLY

   1. Push the fuel tube joint of the fuel tank main tube sub-assembly onto the plug of the fuel suction plate sub-assembly, then install the tube joint clip.

      

      *A	for Sedan	*B	except Sedan
      *1	Tube Joint Clip	-	-
      *a	Fuel Tube Joint	*b	O-ring
      *c	Collar	*d	Correct
      *e	Incorrect	-	-
      	Insert		Insert

      Note:

      • Check that there are no scratches or foreign matter around the connecting parts of the fuel tube joint and plug before performing this work.

      • Check that the fuel tube joint is securely inserted to the end.

      • Check that the tube joint clip is on the collar of the fuel tube joint.

      • After installing the tube joint clip, check that the fuel tank main tube sub-assembly cannot be pushed out.

4. CHECK AIRTIGHTNESS

   1. 

      *A	for Sedan
      *B	except Sedan
      *a	Soapy Water Application Area

      Apply soapy water to the contact areas between the fuel suction tube with pump and gauge assembly and fuel pump gauge retainer.

      Note:

      Cover the connectors of the fuel suction tube with pump and gauge assembly with protective tape.

   2. Install a vacuum pump to port (A) of the fuel suction tube with pump and gauge assembly as shown in the illustration.

      

      *A	for Sedan	*B	except Sedan
      *a	Vacuum Pump	*b	Port A

   3. Close port (B), port (C) and use the vacuum pump to apply 5 kPa (0.1 kgf/cm², 1 psi) of compressed air to port (A) as shown in the illustration.

      

      *A	for Sedan	*B	except Sedan
      *a	Port A	*b	Port B
      *c	Port C	*d	Vacuum Pump

      Note:

      Do not apply more compressed air than necessary.

   4. Check that the contact areas between the fuel suction tube with pump and gauge assembly and fuel pump gauge retainer are airtight.

      Note:

      • If air bubbles appear, remove and reinstall the fuel pump gauge retainer.

      • After a fuel pump gauge retainer and fuel suction tube set gasket have been used once, replace them with new parts.

      • When removing and reinstalling the fuel pump gauge retainer, make sure to clean away the soapy water to prevent the fuel suction tube set gasket from slipping out of position and being assembled incorrectly.

      

      *A	for Sedan
      *B	except Sedan
      *a	Air Bubbles

      Tip:

      If the assembled components are not airtight due to improper installation of the fuel pump gauge retainer, etc., air bubbles will appear as shown in the illustration.

6. CONNECT NO. 1 CHARCOAL CANISTER OUTLET HOSE

   1. Connect the No. 1 charcoal canister outlet hose to the fuel suction tube with pump and gauge assembly.

      Tip:

      After connecting the No. 2 fuel tank evaporation tube and No. 1 charcoal canister outlet hose, check that the No. 2 fuel tank evaporation tube is positioned below the No. 1 charcoal canister outlet hose.

7. CONNECT NO. 1 FUEL EVAPORATION TUBE SUB-ASSEMBLY

   1. Connect the No. 1 fuel evaporation tube sub-assembly to the fuel suction tube with pump and gauge assembly and slide the clip to secure it.
