CAUTION:
Leave fuel filler cap open when tightening nuts, to pre-
vent fuel from flowing out through fuel delivery and
return pipes. Close fuel filler cap after tightening nuts.
Installation is in the reverse order of removal. Do the fol-
lowing:

(2) Ensure sealing portion is free from fuel or foreign
particles before installation.
(3) Tighten nuts in numerical sequence shown in Fig-
ure to specified torque.
Tightening torque:
4.4±1.5 N⋅m (0.45±0.15 kg-m, 3.3±1.1 ft-lb)
