Unplug the inlet, outlet pipe and electrical connector at the top of the fuel filter housing. Take care when disconnecting the fuel coupling as there may still be some pressure in the system.

Reattach the fuel filter housing.
The system will need bleeding so attach one end of a clear hose to the 12mm bleed nipple and the other end into a suitable waste container.
Press the start button (do NOT hold it down), this will start to prime the fuel system, after you have pressed the button go back to the bleed nipple and turn it quarter to half a turn anti-clockwise and hold it there until you hear the fuel pump cut out then do it back up.
Do this about three times until no more air bubbles come out then put everything back together.
