Your fuel filter is an integral part of the fuel delivery system. A clogged filter can cause all kinds of problems, from a rough running engine to leaving you stranded on the side of the road. Volkswagen suggests changing your filter every 30,000 miles but you should change it at the first signs of trouble.

The GTI Mark4 fuel filter is located on the underside of the car, under the right rear seat.

You will need to safely lift and support your car. Please see our article on jacking up your car.

Remove the gas cap to depressurize the system.

I recommend removing the fuse for the fuel pump and starting the car. The car will stall out quickly but it will help in getting a large amount of fuel out of the system. There is still going to be some fuel left in the filter so be prepared for that when you remove it.

Open the left side door and on the side of the dash that you will see a panel. Open the panel and use the included tool to remove the fuel pump fuse. On our car it was the third fuse from the bottom on the row closes to the front of the car. Start the car. It will stall after a few seconds and that will let you know you got the right fuse as well as getting some of the fuel out of the system.

Move to under the car where you will see the filter held in place by a bracket that also holds two other lines and the input and output fuel lines.

Use a screwdriver and remove the clamp and plastic support bracket. You can also move the other two lines out of the way.

Remove the fuel lines from the filter. They are simple push/pull connections. Push in the plastic tab and pull the line off the filter. If yours are a little stuck try wiggling them and pushing the line a little more onto the filter then off. There will be fuel in the filter so be ready to dispose of it correctly.

The fuel filter is designed to flow one direction from the tank to the engine. Make sure you install it in the correct direction.

Installation is the reverse of removal.

Skip Comments: Thanks for your reply Nick - Do you deliver to France? The part i need is either just the connector, however i doubt that the connector is sold separately. Or more likely the connector and fuel hose - leading from the 'out' to the engine!
Can you help
Thanks

Skip Comments: Hello there!
i have attempted to replace my fuel filter. the connector leading from the fuel filter to the engine is decayed and broken. Do i even need this connector, that you show in figure 5 - or can i remove it and simply clamp the fuel hose tightly onto the fuel filter? Thanks Skip
