Your JA Expert,
WARNINGRemoving the fuel pump involves partial dismantling of the car's fuel system. The following points must therefore be observed in connection with the work:Work only in a well-ventilated area! If approved equipment for the extraction of fuel vapours is available, be sure to use it. Wear suitable gloves! Prolonged contact with fuel can cause skin irritation or dermatitis. Keep a class BE fire extinguisher close at hand! Beware of sparks caused by short circuits and when connecting and disconnecting leads in electrical circuits. No smoking anywhere in the vicinity.
IMPORTANT Inspect the fuel line O-rings and replace as necessary.

Important The tank must never be drained by suction through the filler pipe as this will damage the non-return valve!
