4.Check the fuel level with the vehicle on a level surface. If the fuel gauge indicates more than the level as shown (1/2 full), drain the fuel from the fuel tank until the fuel gauge indicates a level at or below as shown (1/2 full).
- In case the fuel pump does not operate, use the following procedure.
a.Insert fuel tubing of less than 25mm (0.98in) diameter into the fuel filler tube through the fuel filler opening to drain fuel from the fuel filler tube.
b.Disconnect the fuel filler hose from the fuel filler tube.
c.Insert fuel tubing into the fuel tank through the fuel filler hose to drain fuel from the fuel tank.
- As a guide, the fuel level reaches or is less than the level on the fuel gauge as shown, when approximately 37 (9-3/4 US gal, 8-1/8 Imp gal) of fuel is drained from a full fuel tank.
