4. Raise the fuel tank and connect EVAP pipe(s).
Tighten
Tighten the fuel tank strap bolts to 46 N.m (34 lb ft).
5. Install exhaust heat shield screws.
6. Connect the fuel sender electrical connector.
7. Install the fuel filler neck clamp (1) to the fuel tank filler extension pipe (2).
8. Install the fuel tank fuel tank filler pipe (2) to the fuel tank fuel tank filler extension pipe (3).
Tighten
Tighten the clamps to 2.5 N.m (22 lb in).
9. Install the bolt (2) to the fuel filler neck (1).
CAUTION: Always apply a few drops of clean engine oil to the male pipe ends before connecting fuel pipe fittings in order to reduce the risk of fire and personal injury.
This will ensure proper reconnection and prevent a possible fuel leak.
During normal operation, the O-rings located in the female connector will swell and may prevent proper reconnection if not lubricated.
