The 1999 Jeep Grand Cherokee's fuel filter is mounted above the rear axle
The 1999 Jeep Grand Cherokee underwent a redesign, and its fuel filter is mounted above the rear axle and near the front of the fuel tank. This is also known as the Jeep WJ model.
The fuel filter is part of the fuel pump assembly, which is located inside the fuel tank. The fuel filter is a combination fuel filter and pressure regulator. It is attached to the fuel pump, which is inside the tank.
The fuel filter is not normally replaced unless fuel pressure/flow testing shows a blockage. However, there is no specified maintenance interval for the fuel filter. It is recommended that the fuel filter be replaced when the fuel pump is replaced.
Some symptoms of a faulty fuel filter include longer than normal cranking times, failure to start on the first try, rough idling, and rough running for the first half block of driving. These symptoms can also be caused by a leaky fuel injector or a failed check valve on the fuel pump, which can allow fuel to drain back into the tank.

The filter is part of a combination fuel pressure regulator
The 1999 Jeep Grand Cherokee, also known as the Jeep WJ, underwent a redesign for the 1999 model year. This model year's fuel filter is part of a combination fuel pressure regulator. This combination filter and regulator is located remotely on the vehicle body, above the rear axle and near the front of the fuel tank.
The fuel filter is attached to the fuel pump inside the tank as a fuel pump assembly, along with a fuel gauge sending unit, fuel filter/regulator, and fuel pump. The filter is located on the drive side frame rail by the gas tank.
The fuel filter/fuel pressure regulator can be replaced without removing the fuel pump module, although the fuel tank must be removed. To replace the filter, first remove the retainer clamp from the top of the filter/regulator, then pry the filter/regulator from the top of the pump module with two screwdrivers.
The fuel system is under constant pressure, even when the engine is off. Always release fuel pressure before servicing any fuel system component.

The filter removes impurities like dirt, rust and water
The fuel filter in a 1999 Jeep Grand Cherokee is located above the rear axle, near the front of the fuel tank. It is a combination fuel filter and pressure regulator, and it is remotely mounted to the vehicle body.
The filter's primary function is to remove impurities from the fuel before it enters the engine. This includes contaminants like dirt, rust, and water, which can cause significant issues if allowed to build up in the fuel system. By trapping these impurities, the filter helps to prevent blockages in the fuel lines and injectors, ensuring the engine runs smoothly and efficiently.
The fuel filter in the 1999 Jeep Grand Cherokee is likely made from a pleated paper element, similar to other fuel filters. This paper element is designed to capture particles larger than the tiny pores in the paper, allowing clean fuel to flow through to the engine. Over time, the paper element can become clogged with debris, reducing fuel flow and impacting engine performance. Therefore, it is essential to replace the fuel filter periodically, with some sources recommending replacement every 30,000 to 40,000 miles or every two years, depending on driving conditions.
The presence of water in the fuel system can have serious consequences, as it can lead to the clogging of injectors. Some fuel filters are equipped with a water separator to address this issue. Additionally, the filter may also use a combination of materials, such as synthetic fibres, to enhance its capacity and efficiency in removing impurities from the fuel.

The 2018 Jeep Grand Cherokee does not have a serviceable fuel filter
The 1999 Jeep Grand Cherokee's fuel filter is located on the driver's side frame rail by the gas tank. However, the 2018 Jeep Grand Cherokee does not have a serviceable fuel filter. Instead, fuel filter replacement may be necessary if certain symptoms arise, indicating a clogged fuel filter. These symptoms include problems with starting the engine, stalling, excessive vibration while driving, and rough slow-speed cruising.
While fuel filter replacement is generally recommended every five years or 50,000 miles for most vehicles, the 2018 Jeep Grand Cherokee's fuel filter is not designed to be serviced or replaced. This is because the fuel filter in this specific model is internal and part of the fuel pump assembly, located inside the fuel tank.
If you suspect that you have a clogged fuel filter or a fuel leak, it is best to refer to your owner's manual for specific maintenance instructions and intervals. Additionally, consulting a certified mechanic or your local service center is advisable to ensure proper diagnosis and repair.
It is important to note that fuel leaks can be dangerous and should not be ignored. While not as dramatic as portrayed in movies, fuel leaks can lead to fires or explosions, so it is essential to address any suspected fuel system issues promptly and with the necessary expertise.
