What You'll Learn
Locating the fuel filter
To access the fuel filter, you will need to slide under the passenger-side rear of the van, behind the tire. The fuel filter is mounted to the upper part of the fuel tank, almost on top of it, on the right side of the van.
Before attempting to locate the fuel filter, it is important to relieve the fuel pressure in the system. To do this, walk to the back of the van and completely unscrew the gas cap from the fill neck on the gas tank. This will remove the pressure in the fuel filter.

Removing the fuel filter
To remove the fuel filter from a 1999 Plymouth Voyager, follow these steps:
Begin by unscrewing the gas cap from the fill neck on the gas tank. This will help to relieve the pressure in the fuel filter. Next, jack up the rear of the vehicle and place jack stands under the rear jack points. Ensure the van is sitting securely and evenly on the stands.
Now, slide under the passenger-side rear of the van, behind the tire. Locate the fuel filter, which is mounted to the upper part of the gas tank. This type of fuel filter has three fuel lines coming out of it. Position a drip pan under the gas tank, in the general vicinity of the fuel filter.
Using a clean rag, compress the fuel lines on their ends. The fuel lines are attached to the fuel filter by a plastic clip. By compressing the end of the fuel line, you will be able to unlock it from the clip. Pull out on the fuel lines to detach them from the fuel filter.
At this point, you should be able to lower the right side of the fuel tank and gain clear access to the fuel filter. Loosen the bolts on the front strap and the right side of the tank, but do not remove them completely.
Finally, with the hydraulic jack lowered slightly, you can now carefully remove the fuel filter from its housing. Remember to take the necessary safety precautions, such as disconnecting the battery and ensuring proper ventilation.

Replacing the fuel filter
The fuel filter in a 1999 Plymouth Voyager is located on the side of the fuel tank, almost on top of it. It is fairly easy to change. Here is a step-by-step guide on how to replace the fuel filter:
- Park the vehicle on a level surface and engage the parking brake.
- Remove the gas cap from the fill neck on the gas tank to relieve fuel pressure.
- Disconnect the negative side of the battery.
- Jack up the rear of the vehicle and support it securely with jack stands.
- Slide under the passenger side of the vehicle and locate the fuel filter. It is usually mounted to the upper part of the gas tank and has three fuel lines coming out of it.
- Place a drip pan under the fuel tank to catch any spilled fuel.
- Using a clean rag, compress the fuel lines on the ends to unlock them from the plastic clip. Then, pull out on the fuel lines to disconnect them from the fuel filter.
- Remove the old fuel filter from the vehicle.
- Install the new fuel filter by connecting the fuel lines to the new filter and securing them with the plastic clip.
- Reattach the gas cap and lower the vehicle back to the ground.
- Inspect the new fuel filter for leaks. Turn the ignition key on and off five times, cranking the engine on the fifth turn.
- If there are no leaks, the job is complete.
It is important to note that you should never smoke or have any heat sources near the fuel tank when working on the fuel system. Always use safety goggles and ensure the area is well-ventilated.
Additionally, the fuel filter should be replaced according to the vehicle's maintenance schedule, or if there is any fuel contamination, such as foreign fluids, bad fuel, or water in the fuel system. A clogged fuel filter can cause engine operating problems and, in extreme cases, a very old filter may disintegrate, allowing trapped contaminants to reach the fuel injectors.
It is also recommended to change the engine air filter at least once a year or every 20,000 miles, whichever comes first. Regularly replacing the air filter will improve fuel economy and put less strain on the engine.
