What You'll Learn
The fuel filter is part of the fuel pressure regulator
The fuel filter in a 1997 Jeep Cherokee is part of the fuel pressure regulator, which in turn is part of the fuel pump module assembly. The fuel pressure regulator is located on top of the fuel pump module, inside the fuel tank.
The fuel pressure regulator plays a crucial role in maintaining the desired fuel pressure. It achieves this by regulating the amount of fuel returned to the fuel tank. Specifically, it bleeds off a portion of the fuel flow from the fuel pump to the injectors, ensuring a consistent fuel pressure across the fuel injector. This is important because the fuel pressure needs to be consistent across the entire fuel injector, not just at the tip.
A typical "base" fuel pressure is 3 bar or approximately 45 psi. This pressure may need to be adjusted depending on whether the engine is idling or running at high speeds. For example, when the engine is idling, the base fuel pressure will be reduced to maintain the pressure across the injector, as the vacuum in the inlet manifold creates a suction effect on the fuel. Conversely, at high engine speeds, the fuel regulator needs to flow a maximum amount of fuel to match the increased fuel flow associated with higher engine RPMs.
In some cases, an aftermarket fuel pressure regulator may be required to allow for pressure adjustments while maintaining a stable base pressure. This is often necessary when installing performance fuel injectors or a high-flow fuel pump.

It's located on top of the fuel pump module
The fuel filter on a 1997 Jeep Cherokee is located on top of the fuel pump module, inside the fuel tank. It is part of the fuel pressure regulator, which is mounted on the fuel pump module. This means that to service the fuel filter, you will need to remove the fuel tank from the vehicle. However, you will not need to remove the fuel pump module itself.
To access the fuel filter, first disconnect the battery ground cable and relieve the fuel system pressure. Then, remove the fuel tank assembly and clean the area around the fuel filter/regulator. Next, remove the fuel filter/pressure regulator retaining clip from the top of the assembly and replace the old mounting gasket. You can then disengage the retaining clamp from the top of the filter/regulator assembly and discard it. Finally, use two small prying tools to gently pry the filter/regulator assembly out from the top of the fuel pump module.
It is recommended that you change your fuel filter every 5 years or 50,000 miles, although this may vary depending on factors such as your driving habits and where you live. Symptoms of a clogged fuel filter include problems with starting, stalling, excessive vibration while driving, and rough slow-speed cruising.

The fuel tank must be removed to service the filter
The fuel filter on a 1997 Jeep Cherokee is part of the fuel pressure regulator, which is mounted on top of the fuel pump module, located inside the fuel tank. To service the fuel filter, the fuel tank must be removed from the vehicle. However, the fuel pump module itself does not need to be removed.
- Disconnect the battery ground cable and relieve the fuel system pressure. Refer to the Fuel System for the proper procedure.
- Remove the fuel tank assembly.
- Clean the area around the fuel filter/regulator.
- Remove the fuel filter/pressure regulator retaining clip from the top of the assembly.
- Replace the old fuel filter/pressure regulator mounting gasket.
- Disengage the retaining clamp from the top of the filter/regulator assembly and discard it.
- Using two small prying tools, pry the filter/regulator assembly out from the top of the fuel pump module.
- Before discarding the old fuel filter/pressure regulator assembly, inspect it to verify that the O-rings are intact.
- If the smallest O-ring cannot be found on the bottom of the filter/regulator, it may be necessary to remove it from the fuel inlet passage in the fuel pump module.
- Check the condition of the O-rings on the new fuel filter/pressure regulator assembly and clean the recessed area in the pump module where the new assembly will be installed.
- Apply a small amount of clean engine oil to the O-rings and install a new gasket on top of the fuel pump module.
- Press the new fuel filter/pressure regulator assembly into the top of the fuel pump module until it snaps into position. A positive click should be heard or felt.
It is important to note that the fuel filter should be serviced or replaced as part of the routine maintenance of your 1997 Jeep Cherokee. Many car companies recommend changing the fuel filter every 5 years or 50,000 miles, but this may vary depending on factors such as your driving habits and where you live. Regularly checking and servicing your fuel filter can help maintain the performance and longevity of your vehicle.

The fuel pump module does not need to be removed
The fuel filter in a 1997 Jeep Cherokee is part of the fuel pressure regulator, which is mounted on top of the fuel pump module inside the fuel tank. When the fuel filter/regulator assembly needs to be serviced, the fuel tank must be removed from the vehicle. However, the fuel pump module does not need to be removed.
To access the fuel filter, you must first disconnect the battery ground cable and relieve the fuel system pressure. After that, you can remove the fuel tank assembly and clean the area around the fuel filter/regulator. The next step is to remove the fuel filter/pressure regulator retaining clip from the top of the assembly. You should then replace the old mounting gasket and disengage the retaining clamp from the top of the filter/regulator assembly.
It is important to note that when you are removing the retaining clamp, you should use two small prying tools to pry the filter/regulator assembly out from the top of the fuel pump module. Before discarding the fuel filter/pressure regulator assembly, you should inspect the assembly to verify that the O-rings are intact. If the smallest O-ring cannot be found on the bottom of the filter/regulator, you may need to remove it from the fuel inlet passage in the fuel pump module.
Finally, you should clean the recessed area in the pump module where the filter/regulator assembly will be installed. Check that the new O-rings are already installed on the replacement assembly and apply a small amount of clean engine oil to the O-rings. Install a new gasket on top of the fuel pump module and press the new fuel filter/pressure regulator assembly into place until you hear a positive click.

The fuel filter should be changed every 5 years or 50,000 miles
The 1997 Jeep Grand Cherokee does not have an external fuel filter. Instead, the fuel filter is part of the fuel pump module assembly, which includes the pump, regulator, sending unit, and filter. This means that to access the fuel filter, you will need to drop the fuel tank as it is located on the top. While there is no standard tune-up interval for fuel filter replacement, it is generally recommended to replace the fuel filter every 5 years or 50,000 miles, whichever comes first. This is because, over time, the fuel filter can become clogged with dirt, water, or other contaminants, leading to reduced engine performance and, in some cases, engine stalling.
Changing the fuel filter on a 1997 Jeep Grand Cherokee can be a challenging task due to its location. Before attempting any repairs or maintenance, it is important to consult a qualified mechanic or a trusted repair manual specific to your vehicle. They will advise you on the exact procedure and safety precautions for your model.
When replacing the fuel filter, it is essential to follow the manufacturer's recommendations and use only compatible parts. Fuel filters are responsible for ensuring that clean fuel is delivered to the engine, and a clogged or faulty fuel filter can cause significant issues. Contaminated fuel filters can lead to reduced engine performance, difficulty starting the vehicle, and even engine stalling.
While the recommended interval for fuel filter replacement is every 5 years or 50,000 miles, it is always a good idea to regularly inspect and maintain your vehicle's fuel system. This includes monitoring fuel pressure and scanning for any diagnostic trouble codes that may indicate a fuel system issue. Additionally, keeping a record of your vehicle's service history can help you keep track of when certain components, like the fuel filter, were last replaced.
By adhering to the recommended maintenance schedule and promptly addressing any issues, you can help ensure the optimal performance, reliability, and longevity of your 1997 Jeep Grand Cherokee. Remember to consult a qualified mechanic or a Jeep-specific forum for more detailed advice and instructions pertaining to your vehicle.
