15 'O' ring

The fuel pump is a 'self priming' wet type pump which is immersed in fuel in the tank. The fuel pump operates at all 
times when the ignition switch is in position II. If the engine is not started, the ECU will 'time-out' after 2 seconds and 
de-energise the fuel pump relay to protect the pump. The pump receives a feed from the battery via fuse 10 in the 
engine compartment fusebox and the fuel pump relay. The relay is energised by the ECM when the ignition switch is 
moved to position II.

 The fuel pump is retained with a locking ring and sealed with a rubber seal. The locking ring requires a special tool 
for removal and fitment.  An access panel for the fuel pump is located in the loadspace floor below the loadspace 
carpet. The access panel is sealed to the floor with a rubber seal and retained by six self-tapping screws.

The fuel gauge sender is integral with the fuel pump. The sender is submerged in the fuel and is operated by a float 
which moves with the fuel level in the tank.
