Suction Jet Pump, Removing and Installing

Suction Jet Pump, Removing and Installing

Special tools, testers and auxiliary items required

• Wrench for tank sensor (3087)





• Torque wrench (40 to 200 Nm) (V.A.G 1332)





• On vehicles with all-wheel drive the shape of the fuel tank dictates that a suction jet pump unit is required to pump fuel to the fuel delivery unit from the area of the fuel level sensor 2 (G169).

• To remove the suction jet pump, the fuel delivery unit must be removed first.

• A test must only be performed, if the engine stops running due to lack of gasoline, even though the fuel gauge indicates the fuel tank is 1/4 full.
