What You'll Learn
Disconnecting the fuel lines
First, you need to locate the fuel filter. The easiest way to do this is to start at the fuel tank and work your way forward, following the fuel lines to the engine compartment. Once you've found the fuel filter, you'll need to disconnect both fuel lines. It's important to note that the fuel supply lines are under pressure, so before removing them from the hose connection, wrap a cloth around the connection and carefully pull the hose off to release the pressure.
Next, disconnect the 4-pin harness connector and supply and return lines from the flange. To do this, press down on the fuel line connectors to release them. You may also need to remove any clips holding the filter in place; these are usually located on the sides of the cage. If the clips are difficult to remove, you can use pliers to help.
Finally, undo the two 17mm bolts securing the fuel filter in place. The fuel filter should now be free to drop down.

Removing bolts
To remove the bolts on a 97 VW Jetta fuel filter, you will need to first locate the filter housing, which is held to the underside of the car with two 17mm nuts. Once you have found the housing, remove the two nuts and then pull the filter housing off of the threaded studs. You may need to use a screwdriver to help lever the housing off, as there are clips holding it in place.
Once the fuel filter and housing are off the studs, remove the two clamps from either side of the fuel filter. If your Jetta has stock VW clamps, you will need to break these off with a pair of cutting pliers.
If you are also removing the cv joint, you will need to jack up the car, remove the wheels, ball joint, and cv joint so the driveshaft hangs free. You will then need to jack up the engine a small bit and remove the engine mount and lingage, before lowering the sub-frame to give yourself enough room to work. This will enable you to remove the bolt from the box.
To remove the ball joint, you will need to remove the three small bolts that hold it to the control arm. New ball joints are sold with new hardware, so don't worry if the bolts get damaged during removal. Mark the position of the old ball joint before removal, as you can move the new one slightly on the control arm to change alignment. The top of the ball joint is clamped into the wheel bearing housing with one large bolt. If this is difficult to remove, you can use a very large and dull chisel to spread the clamp on the bearing housing.
If the bolts are in a tight spot, you have two options: remove the bracket and take out the cv joint, or use a torch with a rosebud tip to heat the cast iron bracket and be ready to hit the cv joint bearing with a hammer and drive it out.

Replacing the fuel filter
To begin, locate the fuel filter by starting at the fuel tank and following the fuel lines forward to the engine compartment. Once you've found the fuel filter, you'll need to disconnect both fuel lines. It's important to note that fuel may spill out during this process, so be prepared with a suitable container and rags to catch any spills.
After disconnecting the fuel lines, you'll need to remove the fuel filter. The filter is typically held in place by bolts and/or clips. In some cases, you may need to use pliers to remove the clips. Once the bolts and/or clips are removed, carefully lower the fuel filter, being mindful of any remaining fuel.
When installing the new fuel filter, ensure that it is securely fastened in place with the bolts and/or clips. Reconnect the fuel lines, making sure there are no leaks. Finally, start the engine and check for any signs of leaks or issues.
It's worth noting that a dirty fuel filter can impact the performance of your vehicle, so regular replacement is important. Additionally, don't forget to also replace the air filter, breather filters, and any other relevant filters to ensure optimal performance.
