To reduce the internal pressure of the fuel main pipes and hose, first start the engine and then disconnect the electrical fuel pump connector locatednear the fuel tank.
Be sure to reduce the fuel pressure before disconnecting the fuel main pipe and hose, otherwise fuel will spill out.
Disconnect the battery cable from the negative terminal of the battery.
Remove the fuel tank cap.
Disconnect the return hose and vapor hose.
Disconnect the fuel pump connector.
Disconnect the high pressure hose from the fuel tank.
Loosen the two self-locking nuts that hold the tank in position and remove the two tank bands.
Detach the fuel filler hose and leveling hose.
Remove the fuel vapor hose and the fuel tank.
Connect the leveling hose to the tank at approximately 40 mm (1.6 in.) of the filler neck.
When connecting the filler hose, connect the end with the shorter straight pipe to the tank side.
Confirm that the pad is fully bonded to the fuel tank. Install the fuel tank by tightening the self-locking nuts to the tank bands until the rearend of the tank band contacts the body.
Connect the vapor hose and return hose. Attach the fuel hose to the line as shown in the illustration.
Tightening torque High pressure hose flare nut : |
30~40 Nm (300~400 kg·cm, 22~29 lb·ft) |
When tightening the flare nut, be careful not to bend or twist the line to prevent damage to the fuel pump connection.
Connect the electrical fuel pump assembly connector.
Check the hoses and the pipes for cracks or damage.
Check the fuel tank cap for proper operation.
Check the fuel tank for deformation, corrosion or cracking.
Check the fuel tank inside for dirt or contamination.
Check the in-tank fuel filter for damage or restriction.
Test the two-way valve for proper operation.
Using a vacuum hand pump, check the operation of the two-way valve.
Valve pump | Guide lines for acceptance or rejection |
When connected to inlet side | Negative pressure generated and vacuum maintained |
When connected to outlet side | No negative pressure generated |
