How to Replace a Fuel Tank Sending Unit for a 1997 VW Golf

The Volkswagen, or VW, Golf is a small family car that has been in production since 1974. The 1997 model belongs to the third generation of this series, which VW manufactured from 1991 to 1999. The fuel system in a 1997 VW Golf uses a small transfer pump, or sending unit, in the fuel tank to move the fuel out of the tank. The procedure for removing the fuel sending unit is generally the same for most VW cars made from 1993 to 1999.

Instructions

    1

    Raise the vehicle with a floor jack, and support it safely on jack stands.

    2

    Remove the fuel pump fuse from the fuse box under the dashboard, using the list on the fuse box as a guide. Start the engine, and allow it to idle until it stalls from fuel starvation.

    3

    Turn the ignition off, and disconnect the batterys negative cable with a socket wrench. Wrap a clean shop rag around a connection on the fuel line to soak up spilled fuel. Loosen the connection with a socket wrench to relieve the pressure in the fuel system. Tighten the fuel connection, and replace the fuse for the fuel pump.

    4

    Remove the rear seat from the vehicle, and disconnect the access cover under the seat with a socket wrench. Detach the electrical connector and fuel lines from the fuel sending unit.

    5

    Turn the retaining ring for the fuel sending unit counterclockwise with a socket wrench, and remove it from the fuel sending unit. Pull the fuel sending unit from the fuel tank, and empty the fuel in the sending unit into a container approved for gasoline. Discard the gaskets for the fuel sending unit.

    6

    Mount new gaskets to the new fuel sending unit, and install the sending unit in the fuel tank. Fasten the retaining ring to the sending unit with a socket wrench. Connect the fuel lines and electrical wiring to the fuel sending unit. Fasten the access cover for the fuel sending unit, and replace the rear seat.

    7

    Connect the batterys negative cable with a socket wrench, and lower the vehicle.
