Replacing The Fuel Filter In Your '99 Jeep Tj

If your Jeep Wrangler TJ is spitting and sputtering when more power is needed, you may need to replace the fuel filter. The fuel filter is inside the fuel pressure regulator, which sits on top of the fuel pump, outside the tank. It has a large surface area and is considered a lifetime filter, but it can be replaced. You can buy a replacement fuel filter for around $55, and it's possible to install it yourself, but labour costs for a garage to do it for you are estimated to be between $98 and $124.

Locating the fuel filter

The fuel filter on your 99 Jeep TJ is located within the fuel pressure regulator, which sits outside the fuel tank and on top of the fuel pump. This regulator houses the fuel filter and can be accessed by releasing the top clamp that holds it in place. It is important to note that the fuel filter is not designed to be easily changed or removed, as it is considered a lifetime filter by the manufacturer.

To access the fuel filter, you will need to locate the fuel pressure regulator. This regulator is positioned on top of the fuel pump, which is outside the fuel tank. The fuel pump is responsible for supplying fuel to the engine, and the fuel filter plays a crucial role in ensuring that the fuel is free of contaminants. By being located within the fuel pressure regulator, the fuel filter can effectively remove even the finest particulates from the fuel before it enters the engine.

The fuel pressure regulator has a distinct appearance. It resembles a big round cylinder made of a dense, felt-like material. This design allows for a large surface area, enhancing its filtering capabilities. When you locate the regulator, you will notice that it is secured by a metal clamp. This clamp needs to be removed to access the fuel filter inside.

It is important to exercise caution when working with fuel system components. Ensure that you have the necessary tools and safety equipment before attempting any maintenance or repair work. Additionally, it is always recommended to refer to the vehicle's service manual or seek advice from a qualified mechanic if you have any doubts or concerns.

By following these steps and locating the fuel pressure regulator, you can access the fuel filter for your 99 Jeep TJ. Remember that proper maintenance and care of this component are essential for optimal vehicle performance and fuel efficiency.

Removing the old fuel filter

To remove the old fuel filter from your 99 Jeep TJ, you'll need to locate the fuel pressure regulator, which sits on top of the fuel pump. The fuel filter is inside this regulator and can be accessed by releasing the top clamp that holds it in place.

Firstly, loosen the straps of the fuel filter using a flat-head screwdriver. You'll need to do this on both sides of the filter. Then, unscrew the strap in the middle, which holds the filter to the frame. Be prepared for some gas to leak when you remove the filter.

Next, pull the tubes off each side of the fuel filter. This may require some force, but ensure they are fully removed to avoid any gas leaks. Pay attention to the direction the arrows on the filter are pointing—they should be facing towards the engine.

At this point, you may need to use a pair of large screwdrivers to pop out the filter. Place them underneath the filter on both sides and gently lever it out.

Once the old fuel filter is removed, you can discard it and prepare to install the new one.

Preparing the new fuel filter

To prepare the new fuel filter for your 99 Jeep TJ, you will need to purchase a suitable replacement. The fuel filter for this vehicle is located inside the fuel pressure regulator, which sits on top of the fuel pump. It is considered a lifetime filter and has a large surface area, but it may need to be replaced if it becomes clogged or if you are experiencing fuel-related issues.

You can find a replacement fuel filter online or at an auto parts store. Make sure to get the correct part for your specific vehicle. The Omix-ADA In-Line Fuel Filter is a recommended option for the 1997-2004 2.5L or 4.0L Jeep Wrangler TJ models. It provides excellent fuel filtration and meets or exceeds the quality standards of the original factory part.

Once you have the new fuel filter, you will need to locate the fuel filter in your Jeep. It is mounted on the inside of the frame, on the driver's side, near the back driver's side tire. You may need to get under the Jeep from the front of the tire to access it easily. Before removing the old fuel filter, make sure you have a flat head screwdriver and a pair of large screwdrivers handy.

Now, carefully loosen the straps of the fuel filter by using a flat head screwdriver on both sides. Unscrew the strap in the middle, holding the filter to the frame. Some gas may leak when you remove the filter, so be prepared and have rags handy to catch any spills. Next, pull the tubes off each side of the fuel filter. This step may require some force, but ensure that the tubes are fully connected to avoid gas leaks.

With the old fuel filter removed, you can now prepare your new fuel filter for installation. Check that the arrows on the new filter are facing the correct direction, towards the engine. Now, you are ready to install the new fuel filter by pushing the tubes onto each side and securing the straps. Ensure all connections are secure to avoid gas leaks.

Inserting the new fuel filter

To insert the new fuel filter, follow these steps:

Firstly, ensure that the new fuel filter is the correct replacement part for your Jeep Wrangler TJ. The fuel filter should be compatible with the 1997-2004 2.5L or 4.0L models. It is recommended to consult your owner's manual or a Jeep specialist to ensure you have the correct part.

Now, locate the fuel filter. It is mounted on the inside of the frame, at the back, on the driver's side. To access it, get under the Jeep from in front of the back driver's side tire.

Loosen the straps of the old fuel filter using a flat-head screwdriver. Unscrew the strap in the middle holding the filter to the frame. Once the straps are loose, move away from the vehicle, as some gas will leak when you remove the old filter. Pull the tubes off of each side of the fuel filter.

Take your new fuel filter and push the tubes onto each side, ensuring they are pushed on fully to avoid any gas leaks. Make sure the new filter is facing the right way; there should be arrows on the filter, pointing towards the engine.

Now, tighten the straps with your screwdriver to secure the new fuel filter in place.

Finally, check that the new filter is secure and correctly installed, and start the engine. Check for any leaks and ensure the Jeep is running smoothly.

Final checks

Once you have finished replacing the fuel filter, there are a few final checks you should perform to ensure the job has been done correctly and that everything is working as it should.

Firstly, check that the new fuel filter is installed securely and that all the connections are tight. This includes checking that the tubes on both sides of the fuel filter are pushed on securely and that the arrows on the filter are pointing in the correct direction (towards the engine). A loose connection could result in fuel leaking, so it is important to make sure everything is secure.

Next, you should check for any signs of fuel leaks. This includes checking the area around the fuel filter as well as the rest of the fuel system. Fuel leaks can be dangerous, so it is important to make sure that there are no leaks before starting the engine.

Once you are satisfied that there are no leaks, you can start the engine and check for any unusual noises or smells. If there are no issues, take the Jeep for a test drive and pay attention to how it is running. Make sure to drive it in a variety of conditions, such as on hills or at high speeds, to ensure that the fuel filter is working correctly and that there are no issues with the engine performance.

If, during the test drive, you notice any problems such as sputtering, stalling, or a reduction in power, this could indicate that there is still an issue with the fuel filter or another component of the fuel system. In this case, it is recommended to take the Jeep to a mechanic for further diagnosis and repair.
