If you own a 1997 Jeep Cherokee, you may be wondering if your car has an inline fuel filter. Well, you'd be right to wonder because, yes, your car does have a fuel filter and it is recommended that you change it every 5 years/50,000 miles to maintain good day-to-day performance. However, it is built into the fuel pump assembly, so it is not external and cannot be reached by simply dropping the fuel tank.

What You'll Learn
The fuel filter is located between the fuel tank and the engine
The fuel filter in a 1997 Jeep Cherokee is not an external, in-line fuel filter. Instead, it is part of the fuel pressure regulator, which is part of the fuel pump module assembly. This means that the fuel filter is located between the fuel tank and the engine, inside the fuel pump assembly.
In fuel-injected cars, the fuel pump must be disabled before relieving the lines' pressure and replacing the fuel filter. This is done by deactivating the electric pump before starting the engine. To do this, turn the engine off, open the fuse box, and remove the pump's fuse. Check your owner's manual to determine where the fuse is located. Make sure the brake is on and that the vehicle is in neutral or park. Then, start the engine.
Before disconnecting the fuel line, relieve the pressure in the fuel system. Find and remove the relay, then start the vehicle with the relay removed to exhaust the fuel pressure. You may need to disassemble any parts sitting over the filter, such as the intake manifold. The fuel filter is located underneath the vehicle, close to the fuel tank, or underneath the hood, near the engine.
The fuel line may be connected to the filter with clamps, quick-connect fittings, or threaded fittings. If the lines use threaded fittings, you will need a specialty wrench for flare-nuts. If the lines have quick-connect fittings, you may need a special tool to disconnect them. Refer to your owner's manual or consult a local mechanic to determine the type of lines and air filter your car has.

Jeep Cherokee models from 1998 onwards don't have an external fuel filter
If you are having fuel issues with your 1998 or newer Jeep Cherokee, you should monitor the fuel pressure with a gauge when the engine is warm and running rough. You can also scan the system for any stored diagnostic trouble codes.
For Jeep Cherokee models from 1996 and earlier, the inline fuel filter can be found on the passenger side frame rail. However, from 1997 onwards, the fuel filter is built into the fuel pump assembly.
Some sources suggest that all Jeep Grand Cherokee WJ models have two fuel filters: a strainer filter at the bottom of the fuel pump module inside the fuel tank, and one exterior filter within the fuel pressure regulator. However, other sources maintain that there is no external fuel filter on these models.

The filter is part of the fuel pressure regulator
The 1997 Jeep Grand Cherokee does not have an external or inline fuel filter. Instead, the filter is part of the fuel pressure regulator, which is part of the fuel pump module assembly. This combination fuel filter and fuel pressure regulator is located on top of the fuel pump module, which is itself located on top of the fuel tank.
The fuel pressure regulator and filter are not considered serviceable, but they can be purchased separately from the unit and replaced. This can be a pricey option, with one user reporting a price of $60 for a replacement filter purchased on eBay.
If you are experiencing issues with your fuel system, it is recommended to monitor the fuel pressure with a gauge when the engine is warm and running rough. You can also scan the system for any stored diagnostic trouble codes.
It is worth noting that some sources suggest that earlier models of the Jeep Grand Cherokee (1996 and prior) had an inline fuel filter located on the passenger side frame rail. However, starting with the 1997 model, the filter became integrated into the fuel pump assembly.
